Facebook app for Get into my Honda!

Need a facebook app in PHP and MySQL that is called Get Into My Honda "Subase a mi Honda!". The final app will be in spanish, if you can only do in english that's fine, just make the text in a separate language file like [login to view URL] so we can easily change without muffling through code. The user adds the app to his facebook, then the app asks him to create a group for his friend invites. He creates his group and then invites all his friends to get into his honda with him. It sends to their walls a post for this. When they click to join him in his Honda the friend will be asked to accept the app of course, then he will have to upload a picture of himself to our server, small pic, like 50x50 or something of the sorts. Once uploaded this means he has accepted to join his friend in his Honda, or join his group as it would be. Once in the group the original friend can see a list of all the people in his group (his honda) with him. We also need a backend section made for our site to keep track of all groups and users in each group. The DB has to keep track of FB ID's and name, the group names (unique names only), number of members in group, etc., etc. The user page on the FB app as well as allowing them to see how many people and who is in their group in a list with the pics next to the user. It will allow them to see TOP Honda'ers.
