This seems to me borderline meditation...

But in any case, in my view, command line applications are plenty beautiful.

From time to time however, I need to make my perl scripts accessible to people who are not comfortable with command line applications, and in that case, I use perl/tk

Perl/Tk is well documented, with good CPAN support, and is easy to adapt to multiple platforms. And is easy to learn, provided you have a basic understanding of OO programming.

I hope that's of some use!
