You might want to look at: GUI Programming with Python: QT Edition Boudewijn Rempt which is available online at: http://www.opendocspublishing.com/pyqt/ Basically all PyQt and PyKDE applications follow the same basic "startup" procedure (even the analog clock, which is where this is copied from): --------------------- # create a QApplication instance a = QApplication(sys.argv) # create a main widget and set its size clock = AnalogClock() clock.resize(100,100) # attach the main widget to the app a.setMainWidget(clock) # show the main widget clock.show() # start the application's event loop and wait for user input a.exec_loop() --------------------- The difference is in what you set up as the main widget - it can be a QWidget or QMainWindow (or even a QButton for a really simple case) to which you add additional child widgets (in your example a QLineEdit and a QWidget). However, you'll need to figure out how to create the widgets you need, how to set up signals and slots to respond to user actions (like clicking a button), and Boudewijn's book is the best place to start.
