JAVA Property Editor Window, e.g. netbeans

Question

I am trying to create a netbeans window as a property in jframe / jpanel.

Can someone give me a link to a tutorial / example of using the properties window (it should be dynamic, not hardcoded).

PS The netbeans.org tutorial is not what I'm looking for, it's about changing the properties window inside netbeans without putting it in my form / panel.

Thanks,

Congratulations.
