Google Maps API Custom App

We want to create a "world wall" for our fundraising site. This wall will use the google maps api & should have the following functionality: -The consumer fills out a form with fields like: Name, email, zip code, facebook, LinkedIn profile); -This form would also process a paypal payment & then populate a pinpoint on the map/world wall. -If the pinpoint is clicked on within the map, it would popup a small window which would show the fields we define to be displayed from the form they filled out. The map should be fully interactive(zooming in; moving around the map) -We would want a facebook like and/or share this button on the page(we would want to be able to send a link to sign the wall in an email or share on Social media sites) -Also on the side of the page a quick summary of info like how many total signers, how many countries, how much $ has been sent, etc.
