If I understand what you're saying, yes you should be able to do that without any special programming. CPanel has a concept called addon domains where the document root for each domain that you add on is a subdirectory of the main account. So if your main domain is example.com and the document root is /home/example/public_html, you'd go into the CPanel for example.com and create an addon domain for example2.com and its document root would be /home/example/public_html/example2. I believe you can set the addon domains' document root to anything so if you want all of them to have the same content, just set the document root to the same directory for all of them.
Since it's a reseller account, you may or may not have a limit on the number of addon domains you can create under the main account, though.
If you have any questions about this, it's really best to call up your hosting provider since they will be better able to answer this question. (Otherwise, they're not worth whatever you're paying them.
) You can also try the CPanel forums at cpanel.net.
