Java sick GUI that does not pertain to look and feel? [closed]

I wanted to know how people make these sick GUI's in java?

I know how to make the standard crappy one with a nice background, but that is it.

Basically what I am talking about is it looks like they took photoshop an开发者_如何学Cd designed the entire GUI and then painted it to the screen and added buttons and stuff to it that they also made in photoshop. How do I do this and what am I looking for?

Of course I still want the same functionality... haha.
