Streamline ISO creation

I have been researching this problem for some time and cannot seem to find the pieces I need.
I would like to be able to send multiple files or a folder(or paths), along with a password to a server. Once there I would like a password protected, encrpted cd created as an ISO image. I have many users at my company that seem incapable of learning to use burning and encryption software. I am not set upon any specific platform or program(s). I do not require it to be free or open source. I can script multiple pieces togther as necessary. I know the ISO creation in Linux is easiest, but cannot find a scriptable method of password encrption. Thoughts?
