While I already had some minor experience from programming using C++ (and BASIC ages ago..), I found using Python great for figuring out Qt. The best thing about it is that you can instantly rerun the script after changes without the need for tedious compiling. When I need to change the same line 10 times to get it right, that surely adds up.

Setting up Qt/PyQt/Eric was a bit of a hassle, but once I got it all right it sure pays off.
