title: handling modal wxDialog from PyQt application
body: <p>So I am using PyQt to create an application with GUI (QtGui)
  I have other GUIs that are created with wxPython and I want to link between them and my current application.</p>
  
  <p>The problem is: I have a <code>wxDialog</code> that I want to show by clicking on <code>PyQt.Gui</code> button (There is no problem in that) and I want <code>wxDialog</code> to behave like a <code>QDialog</code> (Modal Dialog):</p>
  
  <p>I want it to block its parent window until it finishes (click on OK for example)
  But, all <code>PyQt</code> GUIS are children to <code>PyQt.QtGui.QApplication</code> and all <code>wxPython</code> GUIS are children to <code>wx.App</code>. So, it's like I'm running two different apps. </p>
  
  <p>Is there any solution for this problem?</p>
