What I like about Qt and PyQt is that it is so much more than just a GUI framework.
It's got a powerful set of XML parsing classes, a file system that automatically takes care of the difference in file path formats between Windows, Macintosh and Linux, cryptographic hash classes, and support for SQL databases.
There is also a "settings" class that allows your app to remember settings between executions. Behind the scenes it uses the registry in the Windows environment, XML files on Macintosh, and ini files on Linux.

Mind you, it has been (theorically) possible to do the exact same thing for quite a while, using PyGTK and Glade or Gazpacho on the desktop, and the standard python2.5 runtime on the tablet (which includes PyGTK). Only it didn't really work so well.
Anyway, that is what caught my attention with PyQT/QT Designer, plus no Scratchbox.

I will say I was totally flabbergasted when I copied my PyQt source files over to the N810, raw, and it "just worked." I expected to spend a couple of weeks adapting the code to the Maemo platform.
I have some problems with some of the controls being squished, but I have a feeling it is due to my misusing the "sizePolicy" property of the controls. I don't think is it PyQt's fault, it's mine.

I am going to give PyQt a go - fingers crossed!
I suspect that there are quite a few folks who would like to roll their own IT programs on Windows but find the whole mass of stuff that you have to learn first much too intimidating.

Install Qt, PyMaemo, and PyQt. Then see if Gowan's test program works:

If it does, you are good to go.
If you have questions about programming in Qt, this is a good forum:

Nice move by Nokia -- but it does raise the question of why the same was never done for GTK ? :-)

I was aware of that, but as it happened at the same time Nokia bought Trolltech, I assumed there was a connection. After all, python/pyGTK is technically third-party too (through INdT), but it happened because Nokia wanted it to...
It's nice to see that Qt better fulfills that promise. I'll give it a go when I'm tired of my plain but natively cross-platform python web apps :-)
