OGL looks the best and simplest solution.
I'm trying to use it for physical / electronic / software simulation.
I use ogl-derived shapes and a custom made property editor.
an example can be seen here:

There's also another library, called ogllike,
(not maintained anymore I believe),
which might even be more appropriate (has connection points, property 
editor, reshape anchors).

It would be very nice if the standard OGL library could be extended with 
the ogl-like features,
and of course the feature for print  and/or export the canvas.
