Qt con pyqt

[Jean Carlos Rodrìguez]

Hola Lista, saludos desde Venezuela, estoy aprendiendo
python con libros y manuales que hay por la red,
necesito ayuda con Qt designer y pyqt, les explico he
realizado un ejemplo de Qt (el del tutorial Convertir
unidades) luego lo he pasado a python con pyuic...etc
pero al ejecutarlo no pasa nada???
en algunos links que he visto dicen que hay que
colocar otras lineas de código???
Les pido si saben de algun link o algun libro que
tenga mas detalle sobre este tema.
Anexo como me quedo el código después de llevarlo a
python

Gracias, =O)
