I think this falls under the "implement your own widget" heading.
There's some information about this in the tutorial, though
I don't know how up to date it is. Your best bet is probably
to copy the code of one of the existing renderers (depending
on your final licensing requirements) and re-implement the
expose event handler. Also, look at the basic drawing primitives
in the gdk documentation.
