Create a clone of tiddlyspot.com using Amazon AWS

I would like to built a website similar to [login to view URL] I have ideas for the website to become bigger and more expansive than [login to view URL], but for now I'd like a website which duplicates its functionality. The website must be written in Java, preferably using the Play! framework 1.2.4 and the following services should be used from AWS: * S3 for storing each user's tiddlywiki file * DynamoDB for storing user specific information (like passwords) * Route53 for creating dns names. The site will run on a dedicated Ubuntu linux box on AWS. This project is just to make a functional site. It need not have a polished UI, though the UI must not duplicate that of [login to view URL]
