I have never done this as I don't regularly use Mac Os, so I can just 
summarize what I have found when working on the wx backend for matplotlib.

Usually, for a C++ wx application, you would need to have a info.plist 
file and define "NSPrincipalClass" to activate full retina support. I 
don't know whether the @2 icons should work without that. Maybe you can 
try to build wxPython with wxUSE_IMAGE, "compile" an executable and 
define a info.plist for that.

 From looking at e.g. the Qt backend of matplotlib, there must be a way 
to enable Retina support for a Python program without info.plist, but 
this is probably hidden deep inside the Qt sources. It would be great if 
wxPython could support HiDPI displays as well.
