I have an itch to write some software for my n800 / n900 (when it comes). I have only done a few perl scripts so far, but now I need to have graphical output and a UI.

I have not done any proper computer programming for a long, long time - and that was in FORTRAN. I have no experience of C or C++ or any object-orientated programming. I currently do my programming in:

• perl
• MATLAB
• bash scripts

So what is the best language and graphical environment for me to start with? I'm not going to be able to spend a lot of time learning a new language from scratch.
