NetBeans?
 

I can't help but get over the similarities of the app, and the ones that Netbeans gives you as a boiler plate. I would like to consider myself and advert java application programmer and I use Netbeans alot. I was just curious if I hit the nail on the head.
If not to personal, what IDE is used to develp this awesome masterpiece?

Netbeans is primarily used. Shirik and I have had many spirited debates on this... as I prefer Eclipse. ;)

Eclipse > NetBeans
