Actually jscript has email ability, however VERY. It can open the user's email client with the adress bar filled in. It doesn't sound like this is of much help in your case but i just thought you might want ot know.
As far as free hosts, which allow server side scripting languages, try this site:

They are free and support CGI. I have had a pretty good experience w/them.
