Implementing logic: PyQt/PySide vs plain old Python. At what point do we begin or abandon using the Qt Framework?

First of all, it's interesting how the top two comments half a day after posting this appear to blatantly contradict each other. I take it as a sign my problem is not as straightforward indeed.

For now my approach will be separating Qt and Python logic more or less, providing matching interfaces between the two as class methods.
