Lack of documentation of GUI components

[nus-pe-bot]

The app seems to work well with GUI components. The buttons deliver what their names suggest. However, lack of documentation (i.e. the User Guide) means that the user has to infer from the name and learn to use the app by himself, which is very user unfriendly. I have to test the application based on my instinct whether the behaviour of a certain button should work that way. This is unusual. Please add in documentation at least if the app has a functional GUI.
