You don't say whether this is to print yourself or if it is to be professionally printed.

If it's just something you're doing yourself on an ordinary printer, you can buy packs of pre-cut stationery for jewel cases and CD labels which usually include the appropriate software. It's then just a question of dragging in the artwork and inserting text. All the ones I've used have been very simple and intuitive.

If it's to be professionally printed then speak to the printers or CD producers. They'll probably have very specific technical requirements and you may need professional help.
