Typically you might handle WM_KEYDOWN to respond to keyboard input and do your drawing within your WM_PAINT message handler. You can use, for example, InvalidateRect or UpdateWindow in response to WM_KEYDOWN messages of interest to ensure painting occurs as you require.
Draw the rectangle or square with, unsurprisingly, Rectangle.
