I would suggest to use the progress bar component of jquery ui: http://jqueryui.com/demos/progressbar/

If the process you want to monitor runs on the server, you might have to have some kind of javascript background job, that asks the server for the current progress every say 3-5 seconds and updates the progress bar.
