As a high-level answer I would propose to use the Google Maps API or the Google Earth API together with Javascript. This is a good approach to capture user interaction with maps and earth views, retrieve and process geographical user input, setting/displaying placemarks etc.

best to start here

playground with lots of examples (earth, maps, etc.)

If you need dynamical generated KML, you shoud read about NetworkLink. It allows to add link as URL. Your app cat generated KML with placemark and via NetworkLink KML appears in GooglEarth. Read about NetworkLink
