Write a Java program that constructs a Graphical User Interface using JavaFX. The GUI should contain two panes. The left pane should contain three Combo Boxes, one to select a primary color (black, red, green and blue), one to select a background color (white, beige, aliceblue or gold), and one to select a stroke width of lines (1, 3, 5, or 7). The initial primary color is black, the initial background color is white, and the initial stroke width is 1. The right pane is a canvas where it should contain a grid consisting of 36 circles whose outline stroke is black. The inside of these circles should be initialized to white. It is recommended that you create a two-dimensional array of Circle objects with 6 rows and 6 columns, and add them to the right hand side canvas which is a GridPane. It is highly recommended to create nested loops to initialize this array of Circle objects. Note: each circle's radius is fixed and set to be 40. (The size of the applet here is approximately 630 X 540).
