Cgi Work - Help!!!!

I am trying to make a app in CGI to do this:

Background:
It will be used for my clan site
What dose it do:
A admin place where you can add members and upcoming matches, and the member can login every day to see if there are any upcoming matches and when he logs in it will automaticy put the date he loged in and tell the admin that he is active and how long he was unactive, if he was unactive, and it will also do this, if you have not loged in for a week it will automatcly make you unactive, and if a admin can chose to send him a email to say, you have been kicked from the clan if he was unactive for a few weeks, and has not told the admin why, last thing when he logs it will say there is a new match, if there are and he can chose to say, can come, maybe, no, still like that.

So if anyone can help me i would me very happy and give you a big fat kiss :p
