Today I was creating some panels for webshop manager program I'm creating. I used SpringLayout for this. It's really nice, also because I found a class called SpringUtils on java.sun.com somewhere in a tutorial. With this class you can connect the components on a page. And they will be shown in a table-like fashion. At last it's possible, for me, to create nice and professionally looking interfaces using java.
But the strange thing is that when I tried to create the same interface using gtk, I was done in a about five minutes.
