I think that at this stage I will put my version of program on the list, 
though it is more than likely still faulty.  It was renamed to "test.py" with 
Qt Designer output test.ui  which was "compiled" to ui_test.py:

#!/usr/bin/env python
# test.py - a perennial noob testing program
import sys
from PyQt4.QtGui import *
from ui_test import Ui_MainWindow
class StartQT4(QMainWindow, Ui_MainWindow):
    def __init__(self, parent=None):
        super(QMainWindow, self).__init__(parent)
        self.ui = Ui_MainWindow()
        self.ui.setupUi(self)
if __name__ == "__main__":
    app = QApplication(sys.argv)
    form = StartQT4()
    form.show()
    app.exec_()

It does cause reports of segmentation faults, but runs OK on my PC 
 kubuntu 10.03 OS.

I sent this directly to Vikas so as not to clutter the mailing list.  Besides, 
I am not at all confident in my old age that the little program is "fault 
free".   In future right or wrong I will send it all to the mailing list.
