Write a Java program that constructs a Graphical User Interface using JavaFX. Your GUI should contain two sets of four buttons for a text, "Start", "Stop", "Clear" and "Change the text". The first three buttons will be organized horizontally, and there should be a textfield where a user can enter a text, and the button "Change the text" should be under the textfield (see the snapshot of the GUI). Under the button "Change the text", there should be a label "Rate", then below it, there will be a slider that a user can use to change the rate (speed) of a text. Right hand side of the buttons, a textfield, a label and a slider there are panes, each pane showing a text with their initial color. The top should be red and the bottom one should be blue with their background black. The picture below shows a snap shot of the GUI. Each pane should keep printing the given text. (The size of the applet here is approximately 550 X 400).
