Help with Grid Bag Layout

-----------------------------------

Hello,

So as stated I am having trouble using Grid Bag Layout to create a layout for my program I am writing in class.
Now, before I go any farther, what I am writing is beyond the scope of the actual assignment.

So on to the problem, I am creating a layout using the above stated, I have a grid that is 3 columns by 4 rows of space that I will use, you can look at Diagram.jpg in the attached zip file. You can also see the image of the program running and why there is a problem in Error.jpg.

The code in question

Class userInterface()

So first forguve my lack of comments, because I have not finsihing them, but everything is grouped so it should be easy to follow.

The problem is with the addComponent section.

Now that calls a custom method with 5 agruments, the name of the object to create and the 4 corrds, being topx, topy, bottomx, bottomy.

Now if you look at the code it should be layed out like the Disgram, but instead it looks like the Error.

Now from what I can see is that the button push up and do not stay to there locations. they also force off the reset buttons.

So if you have any questions I will read them when I get a chance and any help would be great.
