If all you do is want to collect form submitted data and have it sent to you there are a number of formmail program freely available. I use formmail.php from Tectite.
However, as Colinc states if you want to perform unique and complicated processing on the data then you are going to have to custom-code.
There are gui code generators out there, but they are expensive, difficult to learn and use, and create ugly ugly code.
PHP is not bad, but I only use PHP for quick web based reports but you can do a lot with it if you want. I am starting to do all such work in Perl.
Perl is not hard to learn and has tons of modules out there so instead of coding low level you can focus on what you are trying to do.
