Java Project

[Heironymus]

So guys, I am in a seriously tight spot. I have a project due at midnight tonight, am leaving for work and won't be home until 11:30. I already have half of it completed and the last half I am completely lost. I figured I would post what I have of the code.. what needs to be finished and see if you guys could help me out. I would be more than happy to compensate the person or persons for there help. I hate doing this because it is a my project but I am lost and have severe time constraints.

CheckPoint: Inventory Program Part 4
• 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.

CheckPoint: Inventory Program Part 5
• 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.
• Add a company logo to the GUI using Java graphics classes.

Final Project: Inventory Program Part 6
• Modify the Inventory Program to include an Add button, a Delete button, and a Modify
button on the GUI. These buttons should allow the user to perform the corresponding
actions on the item name, the number of units in stock, and the price of each unit. An
item added to the inventory should have an item number one more than the previous last
item.
• Add a Save button to the GUI that saves the inventory to a C:\data\inventory.dat file.
• Use exception handling to create the directory and file if necessary.
• Add a search button to the GUI that allows the user to search for an item in the inventory
by the product name. If the product is not found, the GUI should display an appropriate
message. If the product is found, the GUI should display that product's information in the
GUI.

Thats what still needs to be done...

This is my code.

Once again.. Thanks for any help you can give... I am lost on this stuff.. programming is not my thing.

I would if I could bro.  Hopefully someone here can help.
