I had made some questions regarding PHP-GTK (there are only 4 php-gtk tagged questions and three are mine) and I end up answering myself because no one answer them.
I know it is a strange language selection but I was attracted to it because it runs on several OSs and the fact that I can reuse some of my code (also the apps end up looking good and I can make little installers in NSIS that just rocks).
Is there a better alternative, that is free (as in freedom) and can run on several platforms?
Both Python and Ruby can work with the GTK libraries. These may be better chocies of languages for you (you’ll certainly get more folk here answering your questions 🙂
