Say I've designed a Java application in NetBeans IDE, with GUI, etc. How would I build a Mac .app file out of it? I have no experience programming on Mac OSX really. I'm sure there is no quick answer, but it'd be cool to be pointed to a tutorial or something. Also, I looked into this a while ago, but is there a free option for creating icons for Mac apps? All I have is Photoshop CS2.
