The X server is required here. QApplication will try to make a
connection to it. QCoreApplication does not - but it brings other
limitations.

Actually there is an easy way to try it out - just set DISPLAY env
variable to nothing:

martin at zenbook:~$ DISPLAY="" python
Python 2.7.6 (default, Mar 22 2014, 22:59:56)
[GCC 4.8.2] on linux2
Type "help", "copyright", "credits" or "license" for more information.
>>> from PyQt4 import QtGui
>>> app = QtGui.QApplication([])
: cannot connect to X server

(the process is aborted)

Cheers
