if your both application are in Qt and you have the source code of both of the application then on Windows you can just send the SendMessage api... or for a platform independent way... google for QtSingleApplication to take some hint.

yes you can call any win32api ... just include <windows.h> whereever you want to use it... but remember that your code will work only on windows then.
