Brian Edwards has put together Java port of winGuiAuto.py. Little does he know that I've been cleaning this up over the last week or so, a version 1.0 release is just days away, and he'll have to do it all over again. Mwahahahahaha!

Seriously, Brian, cool stuff. BTW, you use Coroutine for Java, and say that you are looking for an open source alternative. Well, I gather that there's a Java port of Thomas Heller's fabulous ctypes module in the works: ctypes-java. You might want to take a look.

Also, did you do any of the Python to Java conversion automatically? (It certainly looks like it.) What did you use?
