Example:

import gtk

class SecondWin:

	def __init__ (self, parent):
		self.parent = parent
		self.w = gtk.Window ()

		# Disable interaction with parent
		self.w.set_modal (True)

		# Tell WM this is a dialog
		self.w.set_type_hint (gtk.gdk.WINDOW_TYPE_HINT_DIALOG)

		# Tell WM this window belongs to parent
		self.w.set_transient_for (parent)
		self.w.connect ("delete-event", self.hide)

		box = gtk.VButtonBox ()
		self.w.add (box)

		b = gtk.Button (stock=gtk.STOCK_CLOSE)
		b.connect ("clicked", self.hide)
		box.add (b)


	def show (self):
		self.w.show_all ()
		# Indicate visually that interaction with parent
		# is not possible while we are shown
		self.parent.set_sensitive (False)


	def hide (self, *args):
		# Indicate visually that interaction with parent
		# is possible again
		self.parent.set_sensitive (True)
		self.w.hide ()
		return True


class MainWin:

	def __init__ (self):
		self.w = gtk.Window ()
		self.w.set_position (gtk.WIN_POS_CENTER)
		self.w.connect ("delete-event", gtk.main_quit)

		box = gtk.VButtonBox ()
		self.w.add (box)

		self.sw = SecondWin (self.w)

		b = gtk.Button ("show second win")
		b.connect ("clicked", self.show_second_win, self.sw)
		box.pack_start (b, False)

		b = gtk.Button (stock=gtk.STOCK_QUIT)
		b.connect ("clicked", gtk.main_quit)
		box.pack_start (b, False)


	def run (self):
		self.w.show_all ()
		gtk.main ()


	def show_second_win (self, button, w):
		w.show ()


w = MainWin ()
w.run ()
