Create GUI in a class

I've created a class, which creates the GUI. I would like to add a menubar to it, but I don't really know, how should I add it to the window, if I work with a class. I can't make the menu bar appaer.

class Window(QtGui.QMainWindow):
    def __init__(self, parent=None):
        super(Window, self).__init__(parent)
        Main = QtGui.QMainWindow()


        self.tab1 = QtGui.QWidget()
        self.tab2 = QtGui.QWidget()


        self.figure = plt.figure()
        self.canvas = FigureCanvas(self.figure)


        self.tempLabel=QtGui.QLabel("NC",self)
        self.tempLabel.move(350,20)
        self.tempLabel.setStyleSheet('color: black; font-size: 12pt;font: bold')

        #menu bar
        self.menu=QtGui.QMenu("Port", self)
        self.menu.addAction('&ttyUSB0',)
        self.menu.addAction('&ttyUSB1',)
        self.menu.addAction('&ttyUSB2',)



        self.layout = QtGui.QVBoxLayout()
        self.layout.addWidget(self.canvas)
        self.layout.addWidget(self.tempLabel)

        self.tab1.setLayout(self.layout)

        self.tabs = QtGui.QTabWidget()
        self.tabs.addTab(self.tab1, "Database")
        self.tabs.addTab(self.tab2, "Current")

        self.tabs.show()

The menu bar is usually accessed from the main window, using the menuBar function.

I have edited your example code to show how to add menus, and also fixed a few other minor issues:

from PyQt4 import QtCore, QtGui

class Window(QtGui.QMainWindow):
    def __init__(self, parent=None):
        super(Window, self).__init__(parent)
        menubar = self.menuBar()
        menu = menubar.addMenu('Port')
        menu.addAction('&ttyUSB0')
        menu.addAction('&ttyUSB1')
        menu.addAction('&ttyUSB2')
        self.tab1 = QtGui.QWidget()
        self.tab2 = QtGui.QWidget()
        self.figure = plt.figure()
        self.canvas = FigureCanvas(self.figure)
        self.tempLabel = QtGui.QLabel('NC', self)
        self.tempLabel.move(350, 20)
        self.tempLabel.setStyleSheet(
            'color: black; font-size: 12pt;font: bold')
        self.layout = QtGui.QVBoxLayout()
        self.layout.addWidget(self.canvas)
        self.layout.addWidget(self.tempLabel)
        self.tab1.setLayout(self.layout)
        self.tabs = QtGui.QTabWidget()
        self.tabs.addTab(self.tab1, 'Database')
        self.tabs.addTab(self.tab2, 'Current')
        self.setCentralWidget(self.tabs)

if __name__ == '__main__':

    import sys
    app = QtGui.QApplication(sys.argv)
    window = Window()
    window.show()
    sys.exit(app.exec_())
