Directory browsing with cgi

I´m looking for a script to run on a NT server that can automatically display the contents of specified directories on a site - the same as on which it´s running. I´d also like the script to have an option to set a wildcard mask for filetypes, so that not all files are shown to the user browsing it. And of course, when a filename is clicked, the script should send the file.
So, a script that works like directorybrowsing, just looking better, with the filteroption, and that can be executed on a NT server.
Thanks in advance
