Google Maps and Google App Engine

I have a Google App Engine application that launches a Web Page with Google Map.

开发者_开发百科 I would now like to add functionality to let user sketch on map (which I can probably use JS API for) and then create a fusion table row using python code backend.

Is this possible?

If so how do I transfer the sketch coords from Javascript to Python backend?

Thanks

Here is a simple guideline:

• Javascript and overlays to draw stuff on the maps
• Ajax to post json sketch data from the client to Google App Engine
• A well shaped rest interface on the server using appengine-rest-server
• Fusion-Tables python library to access Google Fusion Tables from GAE
