If you get wxGTK to work, it should be easy to make it work on Windows
and Mac OS X.

I totally support this work. I really wish pgAdmin be compatible with
2.9. This will be a really hard work but a needed one.

But, just to make this perfectly clear right at the beginning, I'm
totally opposed to commit such a patch while wxWidgets 2.9/3.0 is not
available on Linux distros.
