Gmail Account Creator

We want a script that automates the gmail account creation process. It must allow creation of up to 50 accounts at a time...it is fine to request user involvement to enter the captcha. The desired username will be specified and if not available a number may be added to the end. The datafile will consist of a number of desired usernames and the output required is the gmail account usernames and passwords for the gmail accounts created. Proxies will need to be incorporated to prevent shutdown by google after creation of 10 accounts.
