Hello Java forums people

Can you help me? read on...


I am interested in GUI design, mainly user friendliness and related concepts. I want to learn about incorporating an Md5 checksum with a GUI.

A description of intended end user process: Loads java standalone application in JRE, presses scan button action listener all that works, duplicates are deleted, or atleast displayed.

Simple I think.

Any information or links to help me will be much appreciated, I ideally want to learn my example. Also nothing too complicated I want simple code that i can understand, So that I know whats going on.
