Create a GUI program in Java of a basic calculator: 1 screen, 17 buttons. Aside from the mathematical operations working, the following are required:

1. Numbers: all number buttons should work, and the user should be able to form more than 1 digit numbers

2. C (clear button): when clear button is clicked the calc should reset to 0

3. . (dot): the user should be able to form a number with decimal values, but do not let the user use the dot many times in a single number (a number should only have one dot)

Note: The screen should not be editable.
