        self.InitUI()
 
    def InitUI(self):
        self.locale = wx.Locale(wx.LANGUAGE_ENGLISH)
 
        self.menubar = wx.MenuBar()
        self.fileMenu = wx.Menu()
        self.item = wx.MenuItem(self.fileMenu, 1, '&Radio 1', helpString ="Check Help", kind = wx.ITEM_RADIO)
        self.item2 = wx.MenuItem(self.fileMenu, 1, '&Radio 2', helpString ="Check Help", kind = wx.ITEM_RADIO)

        self.item2.SetTextColour((79, 81, 230, 255))
        self.st = wx.StaticText(self, label ="", pos =(200, 200))
        self.fileMenu.Append(self.item)
        self.fileMenu.Append(self.item2)
        self.menubar.Append(self.fileMenu, '&File')
