AWT to Swing Question

I have been trying to convert an AWT app to Swing. I started trying to convert the entire app in one shot and had this same problem. Now I have been slowly adding Swing to the App currently only in the form of JPanels. I can get jpanels to work fine, but when I try to change a Button to a Jbutton

I get:

Exception in thread "main" java.lang.NullPointerException

at java.awt.Container.addImpl(Unknown Source)

at java.awt.Container.add(Unknown Source)

The line of code that it references is just an

add(myJbutton);

If I don't add the Jbutton everything works fine.

And if its a AWT button it works fine.

I figure this is something simple that I'm missing, Anyone know what up from this vague description.?
