Doesn't it?

Sure it can, with pango markup like this:

Gtk::CheckButton b;
Gtk::Label* l=Gtk::manage(new Gtk::Label);

l->set_text("<span background = \"blue\"> blue background </span>");
l->set_use_markup(true);
b.add(*l);

But this will not work for since adding a label to a button will not
work for you, what if you add a call to show_all_children() for the window?.
