Of course I don't know which is the right way for you. I'm very happy with 
pyjamas. It allows you the create client applications in the same manner as 
standalone toolkits like wxWidgets. The message passing between client and 
server is simple done by exchanging json strings (its ajax based of course, 
but this stuff works silently in the background). On the server side there 
are many python toolkits, I prefer cherrypy, others are django and web.py. 

Hope this helps you.
