I'm trying to get a "tool" kind of look and feel application, where someone can upload the files, my perl script already does the needed processing reading those files.Print the results again as a html page.

Limitation is best not to use any webserver

Do you intend this tool to be accessible by the general public or some closed network? You need a Web_Server to process requests, if you mean you want to avoid installing Apache, nginx or whatever, some perl solutions have already been suggested.
