def buildUI(self):
        # To start with we create a layout to hold our UI objects
        # A layout is a UI object that lays out its children, in this case in a column
        column = cmds.columnLayout()

        # Now we create a text label to tell a user how to use our UI
        cmds.text(label="Use this slider to set the tween amount")

        # We want to put our slider and a button side by side. This is not possible in a columnLayout, so we use a row
        row = cmds.rowLayout(numberOfColumns=2)

        # We create a slider, set its minimum, maximum and default value.
        # The changeCommand needs to be given a function to call, so we give it our tween function
        # We need to hold on to our slider's name so we can edit it later, so we hold it in a variable
        self.slider = cmds.floatSlider(min=0, max=100, value=50, step=1, changeCommand=tween)

        # Now we make a button to reset our UI, and it calls our reset method
        cmds.button(label="Reset", command=self.reset)

        # Finally we don't want to add anymore to our row layout but want to add it to our column again
        # So we must change the active parent layout
        cmds.setParent(column)

        # We add a button to close our UI
        cmds.button(label="Close", command=self.close)

    # *args will be a new concept for you
    # It basically means I do not know how many arguments I will get, so please put them all inside this one list (tuple) called args
