Java GUI element design

I want to have custom design for buttons, lists and every element of GUI.

I can see Swing, AWT and other are providing some default design.

Ho开发者_开发百科w can I customize it? Can I customize Swing elements? Any tutorial, documentation?

Look and Feel (Java's tutorial linked) is probably what you mean.

You can use one of the look and feels provided by Java, and if you have to create your own, there's a tutorial here: http://today.java.net/article/2006/09/11/how-write-custom-look-and-feel (but it's quite difficult).
