I asked the question on tkinter-discuss, but the question hasn't shown
up yet.

In the meantime, I have found this:
http://www.ccs.neu.edu/research/demeter/course/projects/demdraw/www/tickle/u3/tk3_dialogs.html

which looks like, if we converted it to tkinter, would do the job, since
all it wants is a list of files.

I have guests coming over for dinner, so it will be much later before
I can work on this.  (And I will be slow -- so if you are a wizard
at converting tk to tkinter, by all means feel free to step in here. :) )
