Thanks for responding, before going into details let me give you some
background: it's back into the days of win32s I did some C++
programming for Windoze using Borland's compiler 'cause MS implemented
a quite strange interpretation of the ARM (and hungarian-notation-
basic-ly-driving-me-nuts :-)

Look at it the way you like best, Tkinter has the elder rights, if
that matters :-)

Have to take this as granted from _the_ Pythonwin authority.

Although embedding the GUI into Delphi is desirable, it's not an
absolute must; for example a loose coupling running the Python GUI as
a seperate task communicating via a pipe (dunno if win32 has pipes)
or a socket with the Delphi program might meet requirements.

If this doesn't work, I'll have to port most of Tk's text widget
functionality to Pythonwin.

Even though sources are available, w/o a machine powerful enough to
run VMware, I'm reluctant of switching to Windows as my development
platform :-(

Maybe it's time to give cygwin a try.
