OK, a C extension allowing to call httrack's "engine" from
a Python program (combined with Python callbacks, of course)
is available in version 0.5 of httrack-py. Not very well 
tested, but it seems to work ;) The documentation is
probably a bit terse for beginners, but feel free to drop 
me a mail, if you have questions.
