Issue
Are there any advantages to hand-coding your Java Swing GUI rather than using the Netbeans Drag n Drop editor? Maybe such as run-time? It seems to me that the Editor auto-creates quite a bit of extra code but I don't know if that has much impact on the runtime of loading the views. The only reason I'm currently using the editor is because it makes the GUI building quick and simple. But are there things you can do only by hand-coding that isn't possible through the editor?
Also is there a better GUI Framework? I've peeked at Java FX, but I really want the kind of effect that the Github desktop software has. It looks so slick and clean, almost like a webapp. Although I'm sure they did that in C++. It just seems to me like there isn't much for Java when it comes to graphics. One of my friends commented that all Java programs look the same and so far it seems true.
I know there are similar posts, but quite frankly they aren't very recent, such as Write gui programatically, or using an advanced gui editor (Java Swing)? which was posted in 2010 or Learning Java Swing (GUI builder or not?) which was also in 2010. If there's nothing new, sorry to bother you.

There are lots, but lets start with the obvious...
- Doesn't lock you into a single development environment. This means your code is sharable to others who may not be using Netbeans. This is of particular importantance when you are using things like Maven based projects
- Encourages you to learn the API. You get a good understanding of how the API actually works and learn plenty of tricks to make fluent and flexible interfaces.
- Encourages greater separation of respobsibilty. It's all to easy to simply keep dragging components onto a form, which does nothing for encapsulation or management. By dividing your UI into areas of responsibility it makes it easier to mange the distinct states and relations between your components. It also makes the code generally easier to read, as you don't need to keep discarding content which is not relevant to what you are trying to figure out.
- Better extendability. Extending components is not easy at the best of times, but is made next to near impossible with form based components (or at least an order of magnitude more difficult)
- Netbeans form editor code is...a mess...
Don't get me wrong, I use the form editor, but I've been hand coding Swing GUI's for ten years before I picked up the form editor. I like the form editor for laying out final screens and tend to use hand coded UIs for every step up to that point, putting the pegs in the hole so to speak.
The short answer is - until you can make a multi-level GUI by hand, stay away from the form designers - IMHO.
I know some people think they make great learning tools, I think the opposite, I think they allow you to develope lazy and bad habits which will affect everything you do into the future.
While the development enviroment shouldn't make a difference, not everyone will want to use Netbeans, best to learn to do without
Also is there a better GUI Framework?
That's rather a matter of opinion. Swing brings a concept of skinning through the use of the look and feel architecture, which provides you with the ability to change the way that components look and feel.
JavaFX provides similar functionality through the use of CSS
Swing is also highly customisable, it's very easy to get into the "paint" level of the components and even generate your own should you want to.
The ability to make a "slick" UI isn't about the toolkit but down to the developer. It's easy to just drop fields and other components onto a container, but it will take a developer with a good understanding of the underlying API and some talent for what actually looks good to make it look "slick".
Pretty doesn't always equal functional. The best UI's are ones you don't have to think about, that don't get in your way and just work. When you've been working with a program for hours, days, weeks, you're not going to be looking at how pretty the UI looks but how well it lets you get what you want done - IMHO
