This layout manager is exactly what I've been looking for - I don't
think I'll ever use gridbaglayout again. IchBin's JGoodies solution
looks great too, but since I already spent way too much time on this, I
wanted to go with a standalone, layout manager only solution - and
since IchBin's already solved the problem with JGoodies there wasn't
any more fun to be had that way.

I still need to install eclipse and look at SWT and netBeans, and
probably the other JGoodies, but it seems at least as far as layout
managers are concerned, I'm all set.

Again: Thanks, everybody.
