title: Cannot import QtGui from PyQt4
body: <p>I have seen this probleme already in many post but none of the answers helped me.
  So, here is my probleme.</p>
  
  <p>I am on windows.
  I have python 3.6 version</p>
  
  <p>1) I dowload a wheel file (PyQt4-4.11.4-cp36-cp36m-win_amd64.whl) of PyQt4 there:
  <a href="http://www.lfd.uci.edu/~gohlke/pythonlibs/" rel="nofollow noreferrer">http://www.lfd.uci.edu/~gohlke/pythonlibs/</a></p>
  
  <p>And I saved it here: C:\Users\Anne-Sophie</p>
  
  <p>2) I open a shell window as admin and I run "pip install PyQt4-4.11.4-cp36-cp36m-win_amd64.whl"</p>
  
  <p>The installation seems to work even if I get the message:</p>
  
  <pre><code>Requirement 'PyQt4-4.11.4-cp36-cp36m-win_amd64.whl' looks like a filename, but the file does not exist
  </code></pre>
  
  <p>When I re-run "pip install PyQt4-4.11.4-cp36-cp36m-win_amd64.whl" I still get this message but I also get <code>"Requirement already satisfied: PyQt4==4.11.4 from file:///C:/WINDOWS/system32/PyQt4-4.11.4-cp36-cp36m-win_amd64.whl in c:\users\anne-sophie\anaconda3\lib\site-packages"</code></p>
  
  <p>3) Now, when I open a python notebook and write "<code>import PyQt4</code>" I don't get any error.</p>
  
  <p>But when I write <code>from PyQt4 import QtGui</code> I get the error message: <code>ImportError: cannot import name 'QtGui'</code></p>
  
  <p>4) I went to <code>C:\Users\Anne-Sophie\Anaconda3\Lib\site-packages\PyQt4</code> and I saw that QtGui was not in PyQt4 but in PyQt4/sip so I write <code>from PyQt4.sip import QtGui</code> this is working....</p>
  
  <p>5) I go to this website for beginers with PyQt4:
  <a href="https://pythonprogramming.net/basic-gui-pyqt-tutorial/" rel="nofollow noreferrer">https://pythonprogramming.net/basic-gui-pyqt-tutorial/</a></p>
  
  <p>And I write:</p>
  
  <pre><code>import sys
  from PyQt4.sip import QtGui
  app = QtGui.QApplication(sys.argv)
  </code></pre>
  
  <p>I get the error: <code>AttributeError: module 'PyQt4.sip.QtGui' has no attribute 'QApplication'</code></p>
  
  <blockquote>
    <p>Finally here are my questions:</p>
    
    <p>Q1: do you think that <code>Requirement
    'PyQt4-4.11.4-cp36-cp36m-win_amd64.whl' looks like a filename, but the
    file does not exist</code> is a problem (step 2) if import PyQt4 is
    working?</p>
    
    <p>Q2: do you know what I am doing wrong? nobody is using <code>from PyQt4.sip
    import QtGui</code> so I am not sure that I should do it..... Moreover,
    even when I do it, I still get error when I go further</p>
    
    <p>Q3: does someone know how to make it work?</p>
