Just create a script which uses a .dat file or a database, and increment the count in the file/database per click that's done.
Easy done with a php script. Use a header to redirect to the site, but have PHP code which increments the count. Then have a simple form, use vbadvanced to make it look official, which contacts the database / file and outputs the number of hits.
Can be taken further, also i could code it for you if you're willing to pay a few dollars pocket money to me
