C#: Need something that follows users in a listBox on Twitter

Hi, I need something that follows users on the mobile Twitter (easier to use than regular Twitter). There will be two listBoxes. One where the user can import accounts that will go follow, and the other listBox is where the user imports the list of accounts that will be followed by the accounts in the first listBox. I need this to be done completely in httpwebrequests. ***I would need the source code of the completed project*** If you think you can do this, please contact me today!
