Thanks for sharing your experience with us.

That's a path we should consider, many schools would benefit from having
gcompris on windows.

Since gcompris rely heavily on the gnome canvas, to my understanding,
this stays a gnome widget, not gtk.
Dia is also based on the canvas if I remember. If this person if
sucessful, does that mean we could port gcompris as well ?
