If you create a bundle then depending on how you run the application you 
may get console output:

  * double click on bundle: no output
  * from command line: open hello.app: no output
  * from console: ./hello.app/Contents/MacOS/hello: output

Or, if you want to avoid creating a bundle in the first place you should 
be able to add this option to your .pro file:

CONFIG-=app_bundle
