I'd fake it with a borderless headerless scrollable form with wide buttons, pretty much imitating the menu items (I keep forgetting the dualism between the names of things in vertical and horizontal menus - they're logically identical, so why double set of names?), each one hiding the form first, then doing its thing. Likewise, you could imitate those with a listbox in such a form.
For positioning, you'd need to do something with catching the mouse position... and hope your user isn't using the keyboard to navigate the menu.
