I'm a reasonably experienced programmer with Perl, PHP and Visual basic. I want to write some custom software for myself at first, particularly a tailored contacts database with a graphic front end which will run in Windows and on the N810.

The only language which springs to mind is Python and one of the GUI kits. Does anyone have any experience/ observations on this? Any advice or pointers in the right direction?
(I probably don't want to run a local web server on either machine.)
