- I am really not sure how to go about this and any help would be great. I have the GUI set up, but not sure what type of text box to use or how to set it to display

Create a uicontrol('style', 'text') with appropriate 'Units' and 'Position' setting. Record its handle somewhere. Then each time the button is pressed, create a random number in the appropriate range and set the String property of the uicontrol to the number.
