@firefly_lightning If you want to learn the foundations well and don't mind taking the long way around? Start with Racket and work through HtDP <htdp.org/>. (Racket probably even has a way to build GUI programs on any system you can install it on.)
If you want to get a to-do list manager up and running? Use Perl to shuffle things in and out of the database, use CGI and a web browser for the GUI, and that'll put you in the space where you can ask @silverwizard for help when you get stuck.
