The error message doesn't really tell you anything, I agree.

1) You don't need to include X11/Xlib.h, but you must include X11/Shell.h

2) In the call to XtAppCreateShell, the widget class parameter should not
   be quoted.  (Maybe you tried quoting it after you got an error because
   Shell.h was not included; it is defined in Shell.h)  Generally, for
   every class of widget that you instantiate, there is a required 
   include file.

These first two caused the error message.  Finally, to get it flying:

3) Replace XtMainLoop() with XtAppMainLoop(MyApplicationContext)
