Do pliku pro dodaj:
CONFIG += console
do pliku CPP ktory startuje twoja aplikacje dodaj 

#include <windows.h>
#include <stdio.h>

w funkcji main(..) dodaj

// detach from the current console window
   // if launched from a console window, that will still run waiting for the new console (below) to close
   // it is useful to detach from Qt Creator's <Application output> panel
   FreeConsole();

   // create a separate new console window
   AllocConsole();

   // attach the new console to this application's process
   AttachConsole(GetCurrentProcessId());

   // reopen the std I/O streams to redirect I/O to the new console
   freopen("CON", "w", stdout);
   freopen("CON", "w", stderr);
   freopen("CON", "r", stdin);
