From what you have written, I would say all of it could be done with AJAX and JQuery, and maybe JQuery UI. Go the JQuery UI site and look at the demos, particularly the modal dialog. You can use JQuery to intercept the hover event over your button and then use and AJAX call to populate and display a tool tip over the button with the message count if you want it to be dynamic and updated whenever you hover over it, else you could return the values from the server with the page and display them all the time next to your button or in response to hovering over it (I am not sure which you want to do). If you did not wish to use AJAX and if you are doing a web forms type of application, you could handle the click event the button (assuming there a server side control) and then redirect the user to a page showing their messages without AJAX or anything particularly interesting.
Anyway, have a look at JQuery UI and see what you think.
