Well, it really depends on how complex you want your paint application
to be.  If it is a very very simple one, you might just stick with the
canvas, and ignore issues like redrawing completely.

But if you are planning on making this a more general application, you
most likely want to use a GtkDrawingArea and paint the exposed regions
on demand and update your internal data structures accordingly.

You can use pixbufs as your backing store for information (you store all
the data there).

I have not worked with GNOME 2 yet, so I cant answer the rest of your
question.
