Comment Box Craziness

I'm not sure how relevant this topic is on this site since it's CSS Creator, not PHP Creator, but here goes:

I need help building a guest book for my website. I have a few PHP files such as:

captcha.php
guestbook.php
guestbook.txt
include.php
sign.php
font.gdf

There's a lot of files and it's pretty confusing, but I've uploaded it to my server and tested it out and it appears to be working because the next page it brought me to said that my comment was posted. I don't even know how to view that comment though...but that's irrelevant because what I want to do is insert it into a DIV on my webpage and have it fit exactly the way the old comment box that I'm currently using does. I like the idea of having a comment box built right into the art gallery instead of having it bring you to a new page where you type in your comment.

The comment box you will see on my page is somebody elses HTML comment box and it offers me little control. I feel bad that I have to use someone else's PHP script but it's a lot of work to learn a programming language when you just need it to make a comment box.

My website is Inkzoid

If anyone could help me it would be appreciated.
