Google Chat on GAE?

Is it possible or any plugins to use c开发者_如何学JAVAhat feature for community page on GAE. Something like gmail chat? maybe some Jquery driven chat?

Have a look to Using Goole App Engine book.
Chapters 8\9 describe how to develop a basic Jquery chat with GAE, here you can download sources of the chapters and here a live coding session.

You should take a look at the google-app-engine-samples. There is an app called geochat that might be a good reference app for what you're trying to do.
