Sorry for the belated answer, I hope it is still of some use.

Dia uses a specialized widget (DiaCanvas) where we write into an
off-canvas array and copy the array into the canvas as an update.  This
may not be the easiest way to go for you, though.  Consider looking at
the stand-alone DiaCanvas2 found on diacanvas.sourceforge.net.

Since you're saying this if for educational purposes, you may be
interested in BlueJ (http://www.bluej.org/), which is a simple UML
editor mean for education.
