Build web application joining QR codes and Twitter

I am looking to create a web application that will merge QR code technology and Twitter API. The user will be able to sign in via their Twitter login, and then be able to create a QR code from any of their Tweets. They can share this QR code with the most popular social applications such as Facebook, Twitter, Wordpress, etc. Pleas do not steal this idea, I'd rather work with you on this. Thank you very much!
