Twitter API + @Anywhere: Automatically send status update & follow someone

Question

How would I get a web app (for example, @Example) to do the following for an authenticated user?

1. Send a status update (send a new tweet, ie. "I just used the new @Example app!")
2. Follow @Example

In one click, using the Twitter API and @Anywhere framework... Can someone point me in the right direction? This is similar to my other question, only that one is for OAuth.

Thanks! ♥
