Looking specifically at the main window stuff, so you can see how *I*
handle the situation.

I Usually create all my windows as a Child of GtkWindow, insert all
the widgets I need in it (if it is static, at least). Then I write
simple wrappers that I connect to specific behaviour on widgets.

As an example, if my app had window that consisted of an GtkEntry for
an address and Cancel and Connect buttons, then I would make a
GtkWindow child, pack everything inside.
Connect to the "clicked" signal on Cancel and inside the handle launch
a "cancel" signal to expose to the outside (with the Window as
emitter), do the same to the connect button. And I'd have a property
"address" in the window, too.

That way, my app has no idea on how exactly things are laid in the
window, I can write the application logic in terms of "business" (a
bit of stretch for a connecter) information and actions (the address
typed, and the cancel or connect actions).

BUT, as I said earler I am a Object Freak... I don't think this is the
ideal way to go, but I feel comfortable with it.

As you can see, in this simple case, there is no need for the Window
to store references for the widgets, since they're not really all that
useful after they're created and I connect to their signals.
