Adding and Removing Components to/from a jPanel

Hello,

I am searching for a way to have a jButton create a remove and create some jComboBoxes, jLabels, and jButtons. I don't know how I could do this. I have some screenshots from NetBeans IDE to help illustrate my problem.

I want the Add Shift button in here...

To do this...

And obviously I would like the remove buttons to remove a shift when clicked.

Well, thanks for any help. I think this is pretty advanced if it's possible. I'm pretty sure I could manage doing this a slightly different way, but it would not look as pretty and I would have to limit the amount of shifts possible. I would otherwise approach this by doing this:

It just isn't as professional. I would do it by just making the components visible and not visible with the button clicks. And changing the attributes of the components is easy. But I would also be limited to however many shifts I placed originally on the jPanel.
