That shouldn't be a big issue though, it is recommended that you
redistribute gtk+gtkmm within your app for windows target. Do not ask
people to install Gtk+Cairomm+Gtkmm themselves.

Maybe I'm talking crack here, but I wonder if Clutter would suit your
needs for the 3D support that you need.
Anyhow, have you reported the gtkglextmm problem to the bindings
authors? Aren't they willing to help you to support the win32 bindings
better?

Erm... Really, that post to migrate to FLTK is totally misinformed an outdated.

On the other hand, to be fair, gtkmm is way more stable than Vala
these days. Note that Vala has not reached 1.0 yet, and it might
experience changes in the short/mid term, the language is not fully
stable yet, and the APIs will definitively change in the meantime,
which will make the application harder to maintain eventually.

I would try to encourage the gtkmm guys to fix the gtkglextmm bindings
on win32 and go ahead with gtkmm from there.
