We've done this using aliens in Newspeak (see ObjectiveCAline and friends). To do a real GUI is more involved, because of MacOS threading issues (which thread is in control etc.). We hope to fix this in time, and of course provide a fully native binding for the Brazil/Hopscotch GUI on macs, as we do on Windows.

Inteoperating smoothly with the rest of the world is very useful.
