This is short example :
1) You can make your own rc file and place it into directory for your 
application
for example:
------------------<custom rc file mygtkrc>----------------------
gtk-theme-name = "Sugarshack"
style "user-font"
{
font_name="verdana 10"
}
widget_class "*" style "user-font"
--------------------------------------------------
2) Then You can reparse this file before main window will be visible :
mygtkrc=os.path.abspath(os.path.join(os.path.dirname(sys.argv[0]),'mygtkrc'))
gtk.rc_set_default_files([mygtkrc])
self.current_setting=gtk.settings_get_default()
gtk.rc_reparse_all_for_settings(self.current_setting,True)


--------------------------example.py-----------------------------------------
#!/usr/bin/env python
# -*- coding: UTF-8 -*-
import pygtk

pygtk.require('2.0')
import gtk
import os
import sys
class HelloGtkApp:
def __init__(self):

self.window = gtk.Window(gtk.WINDOW_TOPLEVEL)
self.window.set_title("Custom gtkrc demo ")
self.window.set_border_width(24)
self.window.set_default_size(210, 80)
self.window.connect("delete_event", lambda widget,event: False)
self.window.connect("destroy", lambda widget: gtk.main_quit())
self.button1 = gtk.Button("Hello")
self.button1.connect("clicked", self.button_clicked)
self.window.add(self.button1)
self.set_custom_rc_file()
self.window.show_all()

def set_custom_rc_file(self):
mygtkrc=os.path.abspath(os.path.join(os.path.dirname(sys.argv[0]),'mygtkrc'))
gtk.rc_set_default_files([mygtkrc])
self.current_setting=gtk.settings_get_default()
gtk.rc_reparse_all_for_settings(self.current_setting,True)

def button_clicked(self, widget,data=None):
message="Button pressed "
self.dialog=gtk.MessageDialog(self.window,gtk.DIALOG_MODAL,
gtk.MESSAGE_INFO,gtk.BUTTONS_OK,
message_format=message)
self.dialog.connect("response", lambda widget,data: self.dialog.destroy())
self.dialog.show()

myapp=HelloGtkApp()
gtk.main()
