Unless you have a really good reason to go to all that effort, you are probably going to add more overhead that it is worth. It will depend on the application. Usually it is just easier to have a user action (Action subclass) go directly to a command that is run on a separate thread, no need usually to have all the request handlers. That is really what the listeners are anyway. All the in between activity really wouldn't make sense for a "Print" request by the user for example. You would just create a print Action, use that action to create various buttons, menu items, etc. Your action class would then contain all the necessary logic to perform the action, do something via swing worker, etc.
In general, don't over architect your application. Keep it simple unless there is a really compelling user requirement to do otherwise.
I hate getting into someone's code and find it burdened with all sorts of unneeded abstraction / modularity. Take the patterns to heart, but only use the bits that make the most sense for your problem.
