It can be static, as long as a it isn't instantiated before Gtk::Main.
What I usually do is to have a function which simply returns a reference
to a static variable defined inside the function body.

Yes, it should just work.  There is a partial specialization for pointer
types which takes care of that.

On a side note, you might want to use a smart pointer instead, or the
memory management will get hairy.  But I don't know your circumstances,
so maybe this doesn't apply.
