Same here. I've been trying to port Tux Paint -- not that porting
should be required for a full-screen X app. For a good while I just
put it aside mainly because nobody was willing to document anything.
(Also: Sugar ate most of the RAM I needed, and my B2 XO is no longer
useful for judging performance on the production machine. I have
since added an SD card for swap.)
Things have changed a tad though, thanks mainly to wiki user "Bert".
The Activity_DBus_API wiki page, though wrong in spots and lacking
some "rainbow" thing, has been a vast leap forward in documentation.

Seeing the same need, I just threw together a demo app. Mind helping?
It builds a *.xo file. When the binary is run on a GNOME desktop,
it gives a 1200x900 window that says hello. There is some commented
out code to do dbus stuff. Most of this was written prior to Bert's
documentation, so perhaps that will help.
Patches are very welcome. If this toy app were to work, then I think
Tux Paint could be fixed as well.
