dirrection for simple record keeping app.

[nephish]

Hey there,
i have been spending some time learning python. i do enjoy it so.
Heres the deal. i need some dirrection advice.
i have a friend that wants me to set up a customer database for him.
Easy stuff like name, phone number, email address. and current status.
he also wants to be able to print this stuff out.
Heres the deal. He runs windows xp.
how could i write something to help him out ? i thought of glade, since
its gtk and gtk can use a windows runtime.... i also thought of making
something web-based and doing this with cgi scripts. but what would be
easier to learn.... using a database like mysql, or writing text files
and reading them to retrieve the info. The scripting itself could just
be a simple dictionary... so........
any suggestions?
thanks
