If the interaction between modules is clean and well-defined, so that separate 'applications' can clearly be seen, you can compile each as a separate .EXE or .APP, and then have a main executable that calls them as appropriate that handles the 'single main menu' and provides the underlying support structures for the whole application.

This is a common approach for other large applications, especailly where there are clearly separate (and preferably, marketable!) modules like accounting systems in the comemrcial environment.
