    ### construction __init__ is crucial

    def __init__(self,x,y):  # x,y sets position
        self.width = 1000
        self.height = 360
        self.window = gtk.Window(gtk.WINDOW_TOPLEVEL)  # window object
        self.window.resize(self.width,self.height)

        ### window closing behavior:
        self.window.connect("destroy",lambda w: gtk.main_quit())
        
        ### boxes for arranging the gui "widgets"
        mainbox = gtk.VBox(False,10)
        self.window.add(mainbox)    # add window to mainbox
        box1 = gtk.HBox(False,10)
        box0 = gtk.HBox(False,10)
        ## why sometimes no 'self.'???

        ### Create gui "widgets"
        self.Bt = [gtk.Button("OK"), gtk.Button("Not OK"), gtk.Button("So So"), gtk.Button("Bad Day")]
        self.delay = [0,0,0,0]   # delay between clicks
        self.entry = gtk.Entry(40)   # text entry/display

        ### adjust sizes of buttons
        for button in self.Bt:
            button.set_size_request(60,20)

        ### pack buttons into boxes
        box0.pack_start(self.Bt[0],True,True,5)
        box0.pack_start(self.Bt[1],True,True,5)
        box1.pack_start(self.Bt[2],True,True,5)
        box1.pack_start(self.Bt[3],True,True,5)

        ### pack everything into mainbox:
        mainbox.pack_start(box0,True,True,5)
        mainbox.pack_start(box1,True,True,5)
        mainbox.pack_start(self.entry,True,True, 20)

        ### connect widgets with "call-back" functions
        i = 0
        while i<len(self.Bt):
            button = self.Bt[i]
            button.connect("clicked",self.bhandler,i)
            button.modify_font(pango.FontDescription("Sans 18"))
            i += 1
        # while
        self.entry.modify_font(pango.FontDescription("Sans 24"))
        # for each button
        
        self.window.show_all()
        self.window.move(x,y)
    # init

    ### event handler for buttons
    
    def bhandler(self,button,id):
        t = time.time()  # system time
        dt = abs(t - self.delay[id])
        self.delay[id] = t
        double = ""
        if dt<0.3: double = "double"
        self.entry.set_text("you "+double+" clicked "+button.get_label()+" "+str(id)+" within "+str(dt))
