Hmmm...
Write the thing yourself, i'd say, its not that hard.
like archbob said, you will have to save the data on the numer of clicks somewhere, file or database doesn't matter, but i think a database is more comfortable to handle...
however.
if you update your db after every click you produce more traffic than necessary, in my opinion. i'd go for capturing the stuff clientsided and sending it to the db every n seconds or when the visitor leaves the navigation page.
if you want help doing that ill be glad to help, but if you want something, code it yourself.
copying is ok to some extent - where it comes to punching in some really dumb code - but that stops where your knowledge stops, i think. if you want or need more, learn it. it's not that hard.
excuse the last if i'm wrong, but i didn't get the impression you were interested in a solution but in the work all done. you will get the first, always, the latter, not.
