The link you provided does everything in ASP. Not sure if thats what you want or not.
If you just want to have the form emailed to you, the easiest (and probably least reliable) way is with mailto
Code:
<form action="mailto:[email protected]" method="POST" enctype="text/plain">
Name: <input type="text" size="15" maxlength="25">
Address: <input type ="text" size="15" maxlength="30">
Comments: <input type="text" size="50" maxlength="255">
<input type="image" src="submitbutton.gif" alt="Submit">
</form>
For putting in a database, you will have to use asp, php, etc. You could use the link you posted, then do a google search on "asp email form" but it is dependant on the mail server you are using. Just add whatever code is needed based on your server.
