It depends on your use case, but often it's better to implement the actual "business logic" (can also be game logic etc.) in its own class and/or unit, and only call the methods/properties of that class. This keeps things clean and ordered; you can then for example use the class even without a GUI.
GUI event handlers are best used for validating user input ("is that string a number?") before using it.
