On Windows, I guess?

Yes, but you will need to program at the C level to do so. Just copy the
way those functions are implemented in a .External call, and you can
do more or less what you like.  There is a pretty general GUI toolkit
available at the C level.

I do appreciate that is probably not what you are expecting, but S-PLUS's
GUI interface was many man-years of work, and that is what you pay for with
S-PLUS.
