For wxWebKit, we use the wxGCDC layer as a 'bridge' between the two.  
So, in your case, you'd code it like so:

def OnPaint(self, event):
	paintdc = wx.AutoBufferedPaintDC(self)
	gcdc = wx.GCDC(paintdc)

	graphics_context = gcdc.GetGraphicsContext()

	# do painting with your graphics_context object

It would be nice to go straight from one to the other, though.

Kevin
