When (or if) I'd finish this low-level gui toolkit, I'd incorporate it
into my original plans, which were: writing a library that provides the
programmer with 1 API, yet can display the GUI in a terminal (curses),
on the desktop(X/win32/...) or in your web browser (DHTML). Terminal
support would likely be very limited though.
I think I'll go ahead and try to write a wrapper around pyglet and start
writing some basic widgets.
