That would of course be a great argument if Python didn't already have
a threading facility, and a standard API for talking to databases with
implementations for all major players.
Python threading is not perfect in many cases in GUI programming -- you
have to implement your own notification mechanism (eg. using queue
polling), as usually you can communicate with GUI only from main
application's thread.
With wxPython, PostEvent (which is what CallAfter also uses) is
threadsafe and can be used from any thread, allowing you to
communicate (in this direction, at least) with the GUI thread
from any regular Python thread. No need for special threads
provided by the framework and, in fact, even though wxWidgets
(on which wxPython is built) provides a wxThread class, it
is not exposed in wxPython because it is redundant there.
