Could some body write me a small program?

Question

Im after a program that will simulate a simple fruit machine It must have a minimum of Three lables which will display the fruit machine symbols - orange-banana-pear-cherry-bar-seven-java (all jpegs)
Two buttons one with the text "SPIN" and the other with the text "QUIT" These buttons will both have actions associated with them.
One lable to show the current credit (i.e. score)
One lable to show the outcome of a spin (e.g "you win 100")
The GUI may include internal Jpanels, use of a grid layout, BorderLayout ect.
The Game. The user should start with 100 credits and the three image lables show the java image (java.jpeg) The current credit lable should show the value of 100. The outcome lable has blank text( "") at the start of the game.
When the user presses the spin button the image lables show 3 random images from orange banana pear cherry bar or seven. Each time the SPIN button is pressed the credit is reduced by 5, the credit label should change accordingly.
Credits can be increased if there is a winning combination of images.
Some challenge eh guys

Answer 1

You guys are being too hard on him, and I'm probably being too easy. Anyway, here's your program. Have fun!
