Hmmm, you might want to wait until the google summer of code is over, we
have a bunch of new functionality coming for the drawingarea widget that
will let you draw on it with cairo, which makes it really quite
powerful.  In addition there are stand alone widgets like gnomecanvas
that could be wrapped into a php-gtk extension and used for your
program.  But right now there is no such functionality.  If you know a
little C the php-gtk devs could use some help ;)
