yes, but you're sending it a Gtk2::Gdk::Window, not a Gtk2::Window.  :-)
try instead

   $plug->window->set_transient_for (Gtk2::Gdk::Window->foreign_new($::XID));

actually, it does check for that --- see gperl_get_object_check() in
Glib/GObject.xs, which essentially says:

        package = gperl_ojbect_package_from_type (gtype);
        if (sv is invalid or not sv_derived_from (sv, package))
               croak()

sv_derived_from is XS-ese for 'isa'.
