GUI using Pygtk and glade

Question

i am trying to build a GUI using pygtk and glade on Windows. I am a noob at python GUI building so please excuse my noobness. I Looked up this tutorial and did exactly as it said. The only difference was that I am on Windows 7 Home Premium x64 .

I put a Label and a button in a window using glade as in the tutorial and then i got a libglade xml file. Then i typed the following code

import sys
import pygtk
import gtk
import gtk.glade

pygtk.require("2.0")

class HellowWorldGTK:

    def __init__(self):

        #Set the Glade file
        self.gladefile = "Hello_World.glade"  
        self.wTree = gtk.glade.XML(self.gladefile) 

        #Get the Main Window, and connect the "destroy" event
        self.window = self.wTree.get_widget("MainWindow")

        if (self.window):
            self.window.connect("destroy", gtk.main_quit)

if __name__ == "__main__":
    hwg = HellowWorldGTK()
    gtk.main()

I put both the files in the same folder and then i run a python interpreter from the command line into the folder.Apparently The program runs but the thing is that i'm unable to get the interface all i get on the command line is that that the Program is running. I dont even get an error or something.Is it due to the fact that i'm on Windows?? I thought that GTK was cross-platform and the same code should run on windows as well as on Linux??

Also here is the .glade file generated by GLADE GUI designer

<?xml version="1.0" encoding="UTF-8"?>
<glade-interface>
  <!-- interface-requires gtk+ 2.24 -->
  <!-- interface-naming-policy project-wide -->
  <widget class="GtkWindow" id="Hello world!">
    <property name="can_focus">False</property>
    <property name="resizable">False</property>
    <child>
      <widget class="GtkVBox" id="vbox1">
        <property name="visible">True</property>
        <property name="can_focus">False</property>
        <child>
          <widget class="GtkLabel" id="Click Here!">
            <property name="visible">True</property>
            <property name="can_focus">False</property>
            <property name="label" translatable="yes">label</property>
          </widget>
          <packing>
            <property name="expand">True</property>
            <property name="fill">True</property>
            <property name="position">0</property>
          </packing>
        </child>
        <child>
          <widget class="GtkButton" id="Please Click on the Button!">
            <property name="label" translatable="yes">button</property>
            <property name="visible">True</property>
            <property name="can_focus">True</property>
            <property name="receives_default">True</property>
            <property name="use_action_appearance">False</property>
          </widget>
          <packing>
            <property name="expand">True</property>
            <property name="fill">True</property>
            <property name="position">1</property>
          </packing>
        </child>
      </widget>
    </child>
  </widget>
</glade-interface>

self.window.show()

At the end of __init__ should do it I think.

EDIT AFTER COMMENT...

self.window = self.wTree.get_widget("MainWindow")

but there is no window called "MainWindow", I think you've called your window "Hello world!", try loading that instead (or renaming your window in glade).

It may be a good idea to check that your window is actially found in the glade file as well.

window_name="Hello World!"
self.window = self.wTree.get_widget(window_name)
if (self.window):
    self.window.connect("destroy", gtk.main_quit)
else:
    raise Exception("I couldn't find the window called "+window_name+"!")
