really, i hate to say it, but the best way is probably to make a PHP script and intigrate it with MySQL, Access, or some other db program. A simple script would be enough to satisfy your needs. i would check out
www.phpfreaks.com for more help/a guide.
Also, i remember there was one program, something along the lines of mojo monkey. im sure a google search is enough.
sorry, but i don't know of any free programs
