Borland's turbo pascal used to have something in this line (w'out user
notes!) - but I expect producing such a tool would drain far too much
programmer time away from core interests

polemic: ten years ago we used to take a class of biologists and teach them
sufficient fortran in a weekend to have them moderately competent
programmers. Now we 'teach' the equivalent classes using GUI packages and
for the most part the students hunt, peck, click and hope through the
options menus ... this modus operandi seems to underlie much of the GUI
philosophy as applied to wordprocessors etc, etc and it gets carried over
to wherever else they encounter the interface including data analysis.
