I don't know what's behind those links, but I surely hope that it covers how to integrate functionality into a GUI.
Because that has been like a secret for years... It's the holy grail.

What kind of functionality are you haveing problems with? I can take note of it and make a tutorial after this one.
Edit: I went through it quickly on my crappy phone. I see you're using swing. Are youmgoing to continue to use swing?
I like swing, don't get me wrong.. I just think that.. I'm about the only one. Maybe I don't know any better

Your not the only one.

I have tried some of the other GUI kits around and while the others
may have better performance, none of them are as easy to use as Swing. I find a lot of people they have problems with Swing and it usually stems from LayoutManager problems. I also plan to write a tutorial on LayoutManagers too.
