Yahoo main, gmail, hotmail email import script

I need an import tool where a user provides his username and password to a particular webmail client. The tool will then extract out all the contacts in the user's email account and display them to an output form with checkboxes next to each email address (format similar to [login to view URL]) On this output page, there should be a "filter" button that when clicked, will list all the email addresses that had their email addresses checked via the checkbox. I would like 3 seperate php scripts - 1 for Yahoo mail, 1 for gmail, and 1 for hotmail. They should all pretty much look and behave the same way. Thanks
