GUI development

Here's a test of any GUI development method.
Start with something simple: three buttons in a frame, laid-out horizontally.
Then perform the following steps, one at a time:
- Add another row containing two buttons, with all their attributes and events/commands.
- Lay out all the buttons vertically.
- Lay out only the first two vertically, with the rest laid-out horizontally.
- Lay out the buttons in groups of two, horizontally.
- Change all the texts of the buttons.
- Remove two buttons.
- Make the layout completely horizontal.
- Change the text of half of the buttons.
- Remove another button.
- Change the event/commands of the remaining two buttons.
- Add back one of the original buttons that was removed in a prior step.
If this becomes a tedious slog then I'd argue that the chosen GUI development method is poor.
