The approach to check JRE installation in GWT is no different from the same check using JavaScript/HTML. You should write a JSNI ( http://googlewebtoolkit.blogspot.com/2008/07/getting-to-really-know-gwt-part-1-jsni.html ) function, which will execute JavaScript logic to determine JRE availability.
First result from the search is this article, which may however, not cover all possible browsers, but is a good start anyway.
