PyGtk/Python 2.0 png transparency help

Question

I've googled and tried to solve this myself for the past few hours to no avail, so i'm hoping someone will be able to help. I installed gmail-notify and decided i wanted to make the popup transparent, so i started looking into the .py file. Even though i'm learning C, and some Assembly, i just can't fully understand python and the gtk library and the frustration is starting to get me. So basically what i'm trying to achieve is to make the image that pops up (background.png) transparent. I'm running stand-alone Openbox, with Cairo. And iv'e made the alpha layers and all that too in the png image. Any help would be greatly appreciated.
