I\'m using the Flamingo ribbon and the Substance Office 2007 look and feel.
Of course now every control has this look and feel, even those on dialog
Here is a library which will automaticaly change the look and feel. I am not sure it this will done for every component in a different way, but you should take a look at it. pbjar.org
This book should be useful if you want to go deep into look and feel /java-look-and-feel-design-guidelines-second-edition
I would be glad to see some code example, if someone can write it, feel free to get starting.
EDIT:
In this forum thread Thread i found the following description
Swing uses a Look & Feel (a PLAF). PLAFs aren't attached on a per-JFrame level. They are attached on a per-VM level. It is almost impossible to mix PLAFs within one application. I have seen a few attempts, all failed.
