I would choose a different approach:
1) Create a static library that contains all the business logic. This 
will be the heart of the application, but does not contain UI.
2) Create a thin application that uses this lib, and that provides the 
commandline version of the interface.
3) Create a simple GUI application that also uses the same lib, and that 
only provides the interactive UI.

I think that would be a much clearer code structure. It will saves you 
lots of hard to read #ifdefs.
