It looks like Netbeans generated code, so only the good lord knows. To the original poster: if you want to understand Swing, ditch the code-generation functions of Netbeans and learn to code it on your own. The Sun Java Swing tutorials are a great place to start. Otherwise you'll be fumbling in the dark. Start here:
