The model should contain data, but it looks like you are trying to put some
view representation in the model, hoping that it magically works. More
importantly, you are adding a non-copyable type - Gtk::Button. You can't
copy a Gtk::Button, because there is no public constructor. If you really
want to, for whatever reason, you can use a Gtk::Button* instead, because
you can copy that.

If you want to create a custom CellRenderer, you might look at the
cellrenderercustom example in the gtkmm tarball:
http://cvs.gnome.org/lxr/source/gtkmm/examples/cellrenderercustom/

But I don't promise that that is as simple as it could be.
