Yes.  Something needs to call gtk.main_quit() to stop the GTK event
loop.  All of this is spelled out pretty well in the tutorial:

http://www.pygtk.org/pygtk2tutorial/ch-GettingStarted.html

Short answer - add this to the Base.__init__():

        self.window.connect('destroy', gtk.main_quit)

When the window is destroyed (ie, closed) then gtk.main_quit will get
called.  Here is the complete code:

import pygtk
pygtk.require('2.0')
import gtk

class Base:
    def __init__(self):
        self.window = gtk.Window(gtk.WINDOW_TOPLEVEL)
        self.window.connect('destroy', gtk.main_quit)
        self.window.show()

    def main(self):
        gtk.main()

print __name__
if __name__ == "__main__":
    base = Base()
    base.main()
