Yes, you can cut and paste and edit in Cakewalk, but there are only so many things that it can do for you, without you actually having to have the manual skills to do what you want to do.
Cakewalk like anything else it is a tool, if you want to learn to string things together more effectively I suggest that you not only learn Cakewalk backwards, but if you haven't already learn some basic music theory too.
In the long run it can only make your stuff better.
