Non-GUI option

Just a few clues I’ve found about running the same binary without a GUI:

1. GTK supports running a program without display:
   http://library.gnome.org/devel/gtk/2.12/gtk-General.html#gtk-init-check. This
   doesn’t tell if it’s possible in wxWidgets though.

2. wxAppConsole of wx 2.9 might be useful somehow. Just replacing
   wxApp with wxAppConsole doesn’t work, I’m not sure how it should be
   used. It’s not very well documented.

3. Another option might be to use IMPLEMENT_APP_NO_MAIN() and make our
   own main method.
