Unless you plan to do statistical analysis with the feedback, you won't need a database; the message simply gets sent to an email address, additional details such as the telephone number are simply put inside the email body text:
from: user@their_email.com
to: contactform@yoursite
subject: Contact form on yoursite.com
---------------------------------------...
telephone: 0123456789
message: hi there, blah blah
Learn html and php for the form processing. You could also use the forms builder app in ultimatewb.
Hello
How can I create a feedback form using HTML or Dreamweaver and connect it to a website server ?
