Java Script code for a EMail form

I have been trying quite unsuccessfully to find a Java script code for an EMail form that allows the user to enter a name and E-Mail address and an autoresponder responds to the users address. It doesn't necesssary have to be Java Script it could be anything but Java Script is just the easiest for me to work with as my code ability is not all that great. I guess I am not in any great hurry as my new domain, which has been registered but not quite yet ready.
