What is so special about them, they are only simple forms that collect information and send them on, either to a database or by email.
The email virsion is very easy, just create a form in html vith as action you php page (action=form.php for example) then create the form.php page, use the mail() function to send the email containing all the insformation collected by the forms. You will need to buy a book or search the net for these instructions but in most php books passing info via forms is about the second thing you learn.
