Changing the components from AWT to Swing is almost painless. The code
will be much easier to maintain. The AWT implementation of visual component
objects has much to be desired.
The naming of most components from AWT to Swing usually includes inserting a
"J" at the beginning of the component name (i.e., "Frame" is now "JFrame"),
and the import statement for the Swing components will be
import.javax.swing.*
Swing components also inherit from Component class, so most underlying code
in regards to overidden methods need not be changed.
The java.awt.TextField used the TextListener interface to listen for changes
to text. The JTextField class uses a DocumentListener interface instead of
a TextListener, so that will have to be changed. The TextListener class is
not used with Swing's text components.
The Swing JList class is substantially different from the awt List class, so
changes will be necessary to convert to a JList.
I am sure that there are other changes, but these are the ones that
predominantly come to mind.
