where are good netbean tutorial for building UI desktop apps?

I've googled but can't seem to find dedicated tutorial series to building d开发者_StackOverflowesktop UI apps on netbean.

Can someone point to a good site ?

I doubt there are very many tutorials out there on this subject; the NetBeans IDE's GUI editor makes laying out Java Swing GUI components fairly simply -- about ten minutes of experimentation and you should be able to lay out a GUI. As for handling GUI events, triggering changes in the GUI as a result, etc., that requires knowledge of Java Swing for which there are plenty of Java Swing tutorials out there.
