I need to make a web application for mobile phones so that I can transfer balance from a 'recharge sim'(sim used to send balance to other mobile sims) located in whatever country to other 'non-recharge sims' .

Can't find any resource i.e. documentation, tutorial, forum discussion,programming language etc.

Is there any great heart to let me know where to start with, with what materials and the other necessary things plz? is there any such open source project for free download ?

Eagerly Waiting to get the response ASAP.
