The wx.Bitmap code below is looking in the directory from which your 
script is running for the png files. If you're not storing those pngs in 
that directory, then it fails. Let's pretend that you have them stored 
at C:\MyPngs. Then to specify this, you would do this instead:

toolbar.AddSimpleTool(wx.ID_OPEN,wx.Bitmap("C:\\MyPngs\\Open.png", 
wx.BITMAP_TYPE_PNG),shortHelpString = "Ouvrir",longHelpString = "Ouvrir 
une confiiguration")

> wx.BITMAP_TYPE_PNG),shortHelpString = "Ouvrir",longHelpString = 
> "Ouvrir une confiiguration")
>         toolbar.AddSimpleTool (wx.ID_CLOSE,wx.Bitmap("Exit.png", 
> wx.BITMAP_TYPE_PNG),shortHelpString = "Fermer",longHelpString = 
> "Fermer le fichier ouvert")

You can also it using the ArtProvider, like so:

open_ico = wx.ArtProvider.GetBitmap(wx.ART_FILE_OPEN, wx.ART_TOOLBAR, 
(16,16))
toolbar.AddSimpleTool(wx.ID_OPEN,open_ico,shortHelpString = 
"Ouvrir",longHelpString = "Ouvrir une confiiguration")

Finally, here's how to use img2py:

1) Navigate to your wxPython tools directory. Mine is located at: 
C:\Python25\Lib\site-packages\wx-2.8-msw-unicode\wx\tools
2) Copy your png files there (If you're using a command line to do the 
first 2 steps, then skip to step #5)
3) Open a command window (in Windows, go to Start-Run, and type cmd)
4) Change the directory to the one in step 1
5) Run the following command, changing the icon file name and the output 
filename as needed:
    python img2py.py -i myIcon.ico icon.py
6) Copy your newly created Python files to the location where your 
script is and import it in your main script. Then you can use the 
getIcon() method.

I actually blogged about this here: http://www.blog.pythonlibrary.org/?p=13
