[Plugin: PHP Code Widget] Can I put this widget in a wp page?

Hi

I have a php page located here:
http://64.141.114.112/~calvinp5/kathy.php

which I grab some vars from and put them in a link
to this page: http://www.calvinpert.name/auto-login

I need to get the vars I sent over in the link
from this page.

Is this possible?
