 class DynAddObject(QDialog):
     def __init__(self, parent=None):
         super(DynAddObject, self).__init__(parent)
         addButton = QPushButton(u"添加控件")
         self.layout = QGridLayout()
         self.layout.addWidget(addButton, 1, 0)
         self.setLayout(self.layout)
         self.connect(addButton, SIGNAL("clicked()"), self.add)

     def add(self):
         btncont= self.layout.count()
         widget = QPushButton(str(btncont), self)
         self.layout.addWidget(widget)

 if __name__ == "__main__":
     app = QApplication(sys.argv)
     form = DynAddObject()
     form.show()
     app.exec_()

或者通过赋值self.object={}字典，将字典dict的每一个值赋值为QPushButton

 class DynAddObject(QDialog):
     def __init__(self, parent=None):
         super(DynAddObject, self).__init__(parent)
         addButton = QPushButton(u"添加控件")
         self.layout = QGridLayout()
         self.layout.addWidget(addButton, 1, 0)
         self.setLayout(self.layout)
         self.add()

     def add(self):
         self.button={}
         print(type(self.button))
         for i in range(1, 8):
             self.button[i]=QPushButton(str(i))
             self.layout.addWidget(self.button[i])

 if __name__ == "__main__":
     app = QApplication(sys.argv)
     form = DynAddObject()
     form.show()
     app.exec_()

效果：
