I have started the project. And done adding rules to list using my program..

Bt I would like to add a interface which will allow user to save a rule temporarily or permanently. That too using a form which will be popped up when a application program not listed in the rules try to access the internet.. (Something similar to NOD 32 firewall or COMODO firewall interface..)
