;Task:
For a minimal "application", write a program that presents a form with three components to the user:
::* a numeric input field ("Value")
::* a button ("increment")
::* a button ("random")
The field is initialized to zero.
The user may manually enter a new value into the field,
or increment its value with the "increment" button.
Entering a non-numeric value should be either impossible,
or issue an error message.
Pressing the "random" button presents a confirmation dialog,
and resets the field's value to a random value if the answer is "Yes".
