paypal.me affiliate program script with tracking and rapid payments

Hi, I'm considering if it is possible to allow my affiliates to promote my sales page that has [login to view URL] links on it. Then, the affiliate commissions they earn, I rapidly pay them with [login to view URL] I think there may be a good way to make a really, really simple and fast affiliate script with tracking for this, but I'm not sure. You would probably need to know paypal api and some other tracking systems. If you know what I'm aiming at, let's talk. I use wordpress so maybe this can be used also. I want to sell memberships to my site via paypal, get paid rapidly, and pay my affiliates very fast...giving them a super simple payment set up mechanism.
