Before coding by hand all the GUI and event handling you could try netbeans ide. Netbeans is a free open source Integrated Development Environment for software developers. It can run on various platforms.
With that tool you can build very easily your project because it provides GUI builder.
All my projects are developed in Netbeans and I am very satisfied.

But if you want something not so general and something unique like overriding an eventhandler then you should buy a book or more about swing. Amazon has a huge list with books about swing.

My advice: Start with Netbeans, learn how the swing works and then code custom classes by yourself.
