Do you mean you're stepping down as the maintainer of wxd, or just the GDC/CodeBlocks stuff?
wxWidgets look very interesting to me, lots of documentation available from what I can tell. Plus it seems it's easy to grab a device context out of a wxWidget frame, so I could use Cairo with that (e.g. http://code.google.com/p/wxcairo/wiki/IntegratingWithCairo). I think I'll give wxd a try these days. Btw, what is up with the excessive blank lines in the example source files? After every statement there is a blank line, it almost seems like a result of some indenter script that screwed things up. This is easily fixable for my own needs, of course. :)
