Juan Hurtado :

I wrote this guide thinking in the user's who want's develope dynamic application's with the GWT (Google Web Toolkit) in an AMP(Apache,MySQL,PHP) environment's. The basic idea is write a small and very simple application using MySQL and PHP at the server side, and GWT for the client interfaze, using JSON for the communication between the client and the server.

Remember, PHP hosting is the cheapest.
