What about providing a complete example and version/system infos.

import sys
from qt import *

def main():
    a=QApplication(sys.argv)
    w=QWidget()
    a.setMainWidget(w)
    w.resize(400,500)
    w.show()
    a.exec_loop()
    print "1"

if __name__ == '__main__':
    main()
    print "2"

print "3"

This one is working fine. I bet, your problem is somewhere down under 
your MyWindow class.

Problems like this are almost always programmers aka. your fault.
