Hi kashif10,
JEditorPane or JTextPane are the classes to use. You can have both bold and italic for a text portion.
See http://java.sun.com/products/jfc/tsc/articles/ for an overview of articles covering the swing text package.
Or try application SimplyHTML at http://www.lightdev.com/template.php4?id=3 it is open source and has a lot of documentation too.
