What other Java GUI frameworks/libraries should I try?

Question

I've used JavaFX for a few projects and I'd like something else. Preferably, something that loads fast, uses native look and doesn't increase final file size too much. I'm considering SWT, but I'm planning to make this project open-source and it might be inaccessible for many people. Any suggestions?

Answer 1

Swing

Answer 2

for java gui , as in other answer suggest go for swing , but swing is not outdated.
There is new thing in market , JavaFx.
This is the place you should go

Answer 3

D'lite I've tried Swing before and not particularly fond of how it's windows interact with native ones. I was thinking about going back to AWT, but I don't hear good things about it.
Rajat Tyagi Pretty sure I mentioned having used JavaFX somewhere before. It works and all, but I need to open up my program to reflection and it will be removed from standard JRE soon, so I'd like to look at other options.
