Just out of interest, was the problem to do with getting PyQt and PyKDE to
work together? This example shows how PyKDE widgets, like KLed, and
PyQt widgets, like QWidget, can be mixed in an application:

  #!/usr/bin/env python

  import sys

  from PyQt4.QtGui import QVBoxLayout, QWidget
  from PyKDE4.kdecore import ki18n, KAboutData, KCmdLineArgs
  from PyKDE4.kdeui import KApplication, KLed

  if __name__ == "__main__":

      about = KAboutData("LED", "", ki18n("LED"), "1.0", ki18n("LED example"))
      args = KCmdLineArgs.init(sys.argv, about)
      app = KApplication()

      led = KLed()
      w = QWidget()
      l = QVBoxLayout(w)
      l.addWidget(led)
      w.show()

      sys.exit(app.exec_())

Note that the KLed class appears to cause a crash when the application
exits if it hasn't been placed in another widget; in this case, we use a
QWidget.
