Hey there everyone, I am currently working on and Assignment that is due tonight and I feel like I am close but can not exactly get to the end. I would appreciate any feedback possible. Kinda stuck at the moment.
---Modify the Inventory Program to use a GUI. The GUI should display the information one product at a time, including the item number, the name of the product, the number of units in stock, the price of each unit, and the value of the inventory of that product. In addition, the GUI should display the value of the entire inventory, the additional attribute, and the restocking fee.
---Modify the Inventory Program by adding a button to the GUI that allows the user to move to the first item, the previous item, the next item, and the last item in the inventory. If the first item is displayed and the user clicks on the Previous button, the last item should display. If the last item is displayed and the user clicks on the Next button, the first item should display
That is what I must finish and I will post the code I have so far beneath this.

I am having a hard part grasping the GUI part that I need to get to display the Array with. Thanks!
