 A GUI form is built with the help of widgets. These are the graphical components available in the Tkinter toolbar. The basics for using widgets are given below, which is sufficient in many cases.

-A GUI program is created using the {{:tkinter.png}} icon for new Tk/TTK application on the //Program// tab. Widgets can be placed by drag and drop or by clicking on a widget and then clicking in the GUI form. Only absolute layout is supported. This is sufficient for school purposes. Designing a GUI surface with layout managers is much more difficult.
