Lol it might work with a little effort :) please try ! haha

just create one that is static and global in your module :)

Im curious to see if it works, if it does, we can create a c++
plugin that c++ modules can depend on, which could create the Gtk::Main
on your behalf (to avoid problems with multiple c++ plugins loaded).

If it doesnt work, you can use the "parent" argument to fake the type
in glade, and provide extra properties virtually by way of the catalog
(but introspecting the type in an automatic way would be nice).
