Always glad to be of help...

Err... well... uhm... I have to admit, most of it I got by trial&error and analysing code snippets I found on Google.

(Also, I have found that some of my Java knowledge comes in handy from time to time, too.)

Haven't found any real starter tutorials other than the one linked above, but I spend a good deal of time skimming through the PyQt class reference to get a feeling of what classes are there and which ones might be of use to me. It's not complete yet, and quite a lot of methods are more or less undocumented, but it's still a great source of information.

Other than that - like I said, I just more or less camp Google whenever I hit a wall with trial&error. Python and PyQt are pretty popular by now, so chances are every question you have has already been ask in one or more forums/mailing list.
