Recently I was considering the choice of PyGTK or wxPython. They are both rich GUI libraries, and they both are cross-platform ones (well... they work on GNU/Linux and on Windows).
I chose PyGTK, because it has *much* better documentation (I wasn't very happy when I had to look for information in documentation of wxPython - and lose a couple of hours - when I wanted to do something really simple...) and it seems to work stable on Windows. > Let's say someone has big amount of algorithms and > statistical models implemented in Pascal > (not well designed console apps). OT: I would recommend the use of Python + Numeric and, eventually, C (when the performance becomes really crucial). I'm working on genetic algorithms and - for now - the combination of Python and C was the best I got ever. In a few days I will run the first version of GAs implemented with Numeric. -- http://mail.python.org/mailman/listinfo/python-list
