No, I don't think so. I've been using NetBeans for quite some time and so far I can't find anywhere how to change the look and feel. Since NetBeans 5.5, you can preview different sets of look and feel when you design a GUI, but there's still no way to set the look and feel using the IDE. You must code it by yourself.
If there's a way to do it in NetBeans, do let me know because I'm also curious to know
SCJP 5.0, SCWCD 1.4, SCBCD 1.3, SCDJWS 1.4
