In theory this should be possible, see Examples/EnvironmentPrefs for an 
example of a System Preferences plugin. I'm not entirely sure this will 
work because creating Interface Builder palettes does not work 
(yet...), but that's probably because IB does some low-level stuff 
itself.

What I'd do:
- Create iphoto_protocols.py, containing a definition of an 
objc.informal_protocol for ExportPluginProtocol. See 
Lib/Foundation/protocols.py for an example, or create an objective-C 
protocol definition and use Scripts/gen_protocols.
- Write a translation into python of the ObjC code on the webpage you 
referenced
- adapt buildplugin.py from the EnvironmentPrefs example
- build the plugin and try if it works.
