This is a feature of gtk+ to be used mainly for programs generated
by gui builders: I don't think applications should be written in this
manner. What's wrong with:
	$win = new Gtk::Window;
	$win->set_title('title');?

This works that way when you call $object->signal_connect(...).

	$window->add(new Gtk::Button);

Something like that can be achieved using AUTOLOAD tricks, but I
don't' thinks it would be that useful...

What version of the module are you using?
Did you ran perl Makefile.PL --with-gdkimlib?

Gtk-0.1.1[56] broke the compilation of gdkimlib (at least for me).
Using the version from the cvs works here...
I'm going to merge 0.1.16 with the cvs version later today.
