php N00b needs a tutorial or suggestion on how to accomplish something

Here is the scenario:

User enters data into a contact form on wordpress blog (right now I'm using contact form 7) then hits submit. I then need the data transfered to the outgoing URL. For example:

User enters: 123456
Hits submit
New window opens with hxxp://www.g00gle.c0m/data.php?data=123456

How in the eff do I do that? I could use a form but the good ones cost so I should learn how to do it myself via coding.

HAH! Figured it out myself. Thanks for all the help BHW. j/k. I just ended up ripping it from somewhere else.

Awww crap now I need help iframing the offer...darn...
