Oliver, I think you misunderstood what he said.
All you need to do is include jquery in every page by putting the <script> tag in the html under your script tag for your gwt application. I presume this is either in an html file somewhere or part of an html template. Just modify the html to include jquery and have none (not tuna, not chicken) of your modules include it (it's included already). If a module doesn't use it there shouldn't be any problems with including it.
