In theory, I agree with what you're trying to achieve here. However,
in practice I think there would be better places to direct your energy
- keeping in mind Windows takes up about 2GB of disk space these days,
12MB of DLL's for each of the maybe 10 Gtk apps I have on Windows
really doesn't make much of an impact, and using shared libraries
probably always be more fragile than just bundling them (extra
complexity always introduces bugs). App developers have to manage
their own updates on Windows anyway, so keeping deps as well as the
actual app up to date shouldn't be any extra effort. Do you any other
reasons for doing this?

I don't want to demotivate you here, my point is just that there is a
lot of work to be done to get Gtk+ 3 up to scratch on Windows (writing
an entire theme engine, for example) so we need to be smart about what
we spend time on.
