Well, "no" is never correct when we deal with software ;-)

But yes, it should be quite a project.  The basic problem here is that
menus are not displayed by the Emacs display engine, they are
displayed by a separate code (which we "stole" from X11).

Displaying pop-down menus with our display engine is "tricky", as the
TTY menus experience amply shows.
