Google cloud messaging with CCS [closed]

Question

I am new to GCM and have a few questions regarding an app implementation. The app should be capable of upstream messaging. So -

1. Do I have to create a server (lets say in Google App engine) which will communicate with GCM. And then GCM will send the message to the app. Or I can do it just with CCS connection and my device can send message to app on another device without a server?
2. Is there a code example of writing server side code which I can use in App Engine? I badly need some tutorial/code implementation on CCS to understand the logic. I dont think android developer site is enough to understand things clearly.

Help appreciated!!
