I received a task to write a program simulating the operation of a dot-matrix printer. There should be 2 modes:
- Entering a symbol and the screen should display the matrix of this symbol; Example:

- Enter the lines of the matrix and display the resulting symbol on the screen; Example:

It is necessary to display the matrix 11 * 9.
Question: what is the easiest and fastest to write? JavaFX or Swing? Or generally WinForms and C #? Experience with none of the above. The output in the console does not fit, you need something similar as in the pictures above.
He himself is a little familiar with Java, but did not do programs with a graphical interface.
