diff between wxPython and python-wxGTK

Hi,
I’d like to install the latest wxPython 2.8.11 and the one-click has a entry for wxPython 2.8.11. But I did not use the one-click wxPython to install wxPython 2.8.10 I used python-wxGTK. So the question is what is the difference between the two
python-wxGTK and wxPython on the one-click site???
