python pyQt connect to sqlite

The following is a simple UI, it contains the label, lineEdit, checkbox and combobox components.
When I press the button, I want to insert those data of components to sqlite , but I do not know how to use.
I checked a lot of information on the Internet , but it always shows that connect to sqlite with C++.

#!/usr/bin/python
# sqlite_test.py

class MainWindow(QtGui.QMainWindow):
    def __init__(self):
        QtGui.QMainWindow.__init__(self)
        self.resize(450, 250)
        self.setWindowTitle('sqlitetest')

        name = QtGui.QLabel('Name :', self)
        name.move(100, 10)
        nameEdit = QtGui.QLineEdit(self)
        nameEdit.move(140, 10)


        age = QtGui.QLabel('Age :', self)
        age.move(100, 50)
        ageEdit = QtGui.QLineEdit(self)
        ageEdit.move(140, 50)

        gender = QtGui.QLabel('Gender :', self)
        gender.move(100, 90)
        self.cb = QtGui.QCheckBox('boy', self)
        self.cb.move(150, 90)
        self.cb = QtGui.QCheckBox('girl', self)
        self.cb.move(200, 90)

        habit = QtGui.QLabel('Habit :', self)
