You're shadowing you variables...
You declare statesComboBox as an instance field in your class...
private JComboBox statesComboBox;
But when you initalise it within your constructor, you declare it as a local variable...
JComboBox statesComboBox = new JComboBox(statesStrings);
This means you ActionListener is trying to use a null references (the instance field)
I am using MySQL server 5.6 to host a database that I am using to manage part number records. I have a Java client front end. My connections between the client and database are all good. In my panel to create parts, I have a JComboBox-typeComboBox that is populated by querying the database for all possible part types and displaying their type numbers in the drop down menu. Depending on the selection from that JComboBox the tdescripTextField and seqTextField are filled with the the appropriate information but I can not get the JComboBox-matComboBox to be populated by the appropriate results that are queried using the selected PartType number.
I have used a number of System.out.println(); to debug the part of the code where the issue is happening, and from what I can tell the String[] mats does contain the correct information, but it just wont assign it to the matComboBox. I notifced if I don't initialize matComboBox = new JComboBox(); right after the typeComboBox I get a compilation error saying that matComboBox is null.
Thanks in advance for any help.
p.s. all of my query methods return JSONArrays from the database.

You already have a combo box, which is already displayed in the panel. What you want is to popule this already existing combo box.
But your code does
matComboBox = new JComboBox<Object>(mats);
So it creates another JComboBox, populated with the mats that you retrieved. That won't popukate your existing, displayed combo box. What you need to do is to change the data inside the combo box:
matComboBox.setModel(new DefaultComboBoxModel(mats));
I am awful at Java GUI and used a generator to make most of the GUI for me. I made it in Netbeans and then copied it over to Eclipse. It lags out my pretty powerful computer for about 5 seconds on start and although I've tried timing it and stuff, I can't figure out why. I don't like to blame the generator but it is 100% coming from that UI code.
I would really appreciate someone helping me figure out what is causing it, and just in general improving the ugly UI code. The other code is unfinished, and this is just the interface part.
note that you can remove all of my code, even the gridLayout, and it will still lag, and if i compile it to a .jar and compile it with a -classpath argument it has the same lag

I am having problems in setting the GroupLayout as desired in Java.
My code is given below. The desired placement for components is:
++++++++++++++++++++++++++++++++++++++++++++++++++++
+LABEL_A caseStudyComboBox LABEL_B +
+LABEL_C TextfieldE BtnD +
++++++++++++++++++++++++++++++++++++++++++++++++++++
Instead of the above, the output is:
+++++++++++++++++++++++++++++++++++++++++++++++++++
+LABEL_A +
+ caseStudyCombBox +
+ LABEL_B +
+ LABEL_C IS LONGER THAN A: +
+ TextfieldE +
+ BtnD +
+++++++++++++++++++++++++++++++++++++++++++++++++++
Please suggest some remedy.
Thanks.

Looks like there is a bit of confusion with brackets when you set up horizontal and vertical groups. The controls fall out of the intended groups that you create.
Instead of
layout.setHorizontalGroup(layout.createSequentialGroup()
.addGroup(layout.createParallelGroup())
.addComponent(Label_A)
.addComponent(Label_C)
It should actually be:
layout.setHorizontalGroup(layout.createSequentialGroup()
.addGroup(layout.createParallelGroup()
.addComponent(Label_A)
.addComponent(Label_C))
In first case you're adding labels to the sequential group instead of the parallel group like in the second case.
Here is the result with the following slightly modified code:
layout.setHorizontalGroup(layout.createSequentialGroup()
.addGroup(layout.createParallelGroup(TRAILING)
.addComponent(Label_A, GroupLayout.DEFAULT_SIZE, GroupLayout.DEFAULT_SIZE, Short.MAX_VALUE)
.addComponent(Label_C, GroupLayout.DEFAULT_SIZE, GroupLayout.DEFAULT_SIZE, Short.MAX_VALUE))
.addGroup(layout.createParallelGroup(LEADING)
.addComponent(caseStudyComboBox, GroupLayout.DEFAULT_SIZE, GroupLayout.DEFAULT_SIZE, Short.MAX_VALUE)
.addComponent(TextFieldE, GroupLayout.DEFAULT_SIZE, GroupLayout.DEFAULT_SIZE, Short.MAX_VALUE))
.addGroup(layout.createParallelGroup(LEADING)
.addComponent(Label_B, GroupLayout.DEFAULT_SIZE, GroupLayout.DEFAULT_SIZE, Short.MAX_VALUE)
.addComponent(BtnD, GroupLayout.DEFAULT_SIZE, GroupLayout.DEFAULT_SIZE, Short.MAX_VALUE))
);
layout.linkSize(SwingConstants.HORIZONTAL, Label_B, BtnD);
layout.setVerticalGroup(layout.createSequentialGroup()
.addGroup(layout.createParallelGroup(BASELINE)
.addComponent(Label_A)
.addComponent(caseStudyComboBox)
.addComponent(Label_B))
.addGroup(layout.createParallelGroup(LEADING)
.addComponent(Label_C)
.addComponent(TextFieldE)
.addComponent(BtnD))
);
