There is no more integrated way to do it on Windows.

py2app always automatically includes unicode support (among other 
things that the python internals may want), py2exe does not make any 
such effort to reliably produce working applications on your behalf :)  
See: <http://starship.python.net/crew/theller/moin.cgi/EncodingsAgain> 
(found by googling for: "no codec search functions registered" py2exe)

data_files is a distutils option, and resources is a py2app option.  
The latter is in there because it's necessary in order to specify 
resources on the command line.  They do the same thing, though.  It's 
somewhat questionable that data_files is used for that purpose at 
all... but py2exe does it, so py2app does it too.
