I would suggest Perl/Tk also there is a great book by O'Reilly called Mastering Perl/Tk that has some excellent examples that get you up and running really fast. The dialog boxes and widgets and thangs are pretty easy to wrangle up. Here is the link to the book and I think a lot of the example code can also be found online. Good luck! Mastering Perl/Tk
