Note that you would be better off asking general questions like this in Google's GWT forum or some forum dedicated to web app deployment.

As far as I know, that isn't possible. All the files (JavaScript code, images, html's, etc.) in a compiled GWT module are there because they
should be accessible to the user. There is no magic that will allow access to the compiled JavaScript code only from HTML. The browser asks for *.js files by reference from the HTML in same way it would if a user typed the URL in the address line.
