Welcome to JavaRanch.

Since there seems to be nothing applet-specific in the question, I'll move it to the Swing/SWT forum, where you're more likely to get an answer about this kind of question.

1) Have you tried JTextArea#setBorder(null) or JTextArea#setBorder(BorderFactory.createEmptyBorder(0,0,0,0)) ? Usually you add a JTextArea to the parent after wrapping it inside a JScrollPane. Check out the API for similar border related methods for the JScrollPane

2) If you have added the buttons to a ButtonGroup and one of them is selected, there is no way you can clear all selections. You need to remove them from the group, clear selections and add them back to the group.

And for previous versions of Java you can use a JRadioButton that is not shown in the user interface, and set that as the selected button.
