I wouldn't use JTextArea for anything except prototyping. It has the bitter functionality of notepad. But it's up to you.

I would use a JEditorPane or JTextPane. I know you can't size it based on character size but that's for the best. For word wrap, you can do setContentType("text/html"); and wrap the text in <'p><'/p> tags.

(Note you still use JScrollPane for scrolling. In fact, the scroll pane works for any component)
