I need some Java friends / mentors / co-learners

Okay, so if anyone is interested, here is a first pass at Java Swing version of Conway's Game of Life.

I am seeking hard critical responses with suggestions for improvement to make it more Java-esque or Java-licious or otherwise unlike someone who has been programming in C/C++ for 30 years just trying to learn new syntax.

I am also open to corrections to obvious bone-head or ham-fisted mistakes.

@Absinthe could be some kind of markdown nonsense I can't see but no link!
