Programming Forums - Visuals in Swing

I'm making a Java based survey. For some reason the survey isn't looking right when I change the size of the window.

Basically, buttons, labels and radio boxes will vanish when the window isn't the right size. How would I make it so that the items (label, buttons...) inside the Applet window fit the content of the box more snug?

Here's the default size:

While here's how it looks after messing with the applet size (which is what the user can do).
