In fact, from my beginner point of view, it seems like the python world is more suitable for a quickly-developed and fun web application. And, on t...

I'm trying to get some server side stuff going for my GWT project.

Recently I've been very interested with GWT and Google App Engine. Although I know little of the latter, I think I have a basic understanding of what is it. From what I've read (and using my novice computer science comprehension) I've come up with: Google App engine is a service that allows you to host your code on Google servers. Once...
