I guess not too hard, as long as you can get to the raw color data.
The problem I had, was that I needed to convert from BGRA to RGB data.
I added a function to the pycairo binding for it. As you can see in the
example below.

-- begin code
def OnPaint(self, event):
	cairo.write32BGRAto24RGB(self.imageData, self.image24, WIDTH,
HEIGHT)
	self.image.SetData(self.image24)
	
	dc = wx.PaintDC(self)
	bitmap = self.image.ConvertToBitmap()
	dc.DrawBitmap(bitmap, 0, 0, False)
-- end code

Btw, are you using windows or linux or ... ?
I have a win32 installer executable ready for Python2.3
