Seems like it might be easier to write a makefile :) 

Do you really mean that you plan to not use makefiles? If not you might
just want to change the command on a session basis. You do know that you
can backspace over the make -k and simply type g++ -Wall -g file.cpp and
that will become the new command until you close emacs. I tend to do
that when working on small throwaway programs. 

Another idea, if you don't like what Eli suggested earlier is to come up
with a makefile template and use auto insert. I have a template that I
only need to basically change the list of files in and it save a lot of
time during the compile, run. scream. debug, edit cycle.

Finally, you can edit the compile command for all time but it seems like
a bad idea.
