QR Code Generator and COde Tracking

I want an Online QR Code generator and once the code it created I need a back end tracking system. I want the QR code Generator to include but not limited to: Text Website URL Telephone Number SMS Message Email Address Email Message Contact Details (VCARD) Event (VCALENDAR) Google Maps Location Wifi Login (Android Only) Paypal Buy Now Link Social Media iTunes Link YouTube Video I want the tracking to be able to track scans, clicks and have a Shortened URL plugin. I Am pretty sure the QR Generator is Java Script, not sure what the backend database for the tracking would be best. I am looking for suggestions, and options. I have Linux and Windows hosting platforms. Maybe in the near future I would like to be able to have a little downloadable app the clients can place on there PC to create QR's and download the Stats. Not sure all of the details. Also possibly designing the website. A MUST is an easy to use Interface for the end user and have a nice GUI.
