What is the best GUI framework for Windows in Python?

Question

Python

I need to write a desktop application for Windows in Python.
What it will do:
- parse exel and save data to sqlite
- save data to sqlite from GUI forms
- generate exel from data to sqlite -
create/delete files/directories
installing all sorts of Qt and some additional libraries, roughly speaking downloaded-installed-launched.
I am looking into tkinter, pygobject and wxPython.
I have never done anything under Windows before, so there are some stupid questions - if you take pygobject, which, as I understand it, uses GTK, is there a guarantee that GTK is on Windows older than 7? Same question for wxPython.
Therefore, I tend to tkinter, since it works by default (or not?).

If you don't need any tricky widgets (multi-window applications), then take tkinter - it doesn't weigh much, it packs well in pyinstaller~, you can even file your own Temko. But tk is as old as mammoth shit - so there are no complex controls like a calendar and others in it (except perhaps as plugins installed separately).
GTK it will still be fatter, but about all sorts of Qt and wx.
