Matters if you designing the content of the CD or a CD Cover or CD case. CD content can be done through garage band if its music or windows movie maker for video as well as you can burn disks on winidows media player and ituens. Designing CD covers can be done on applications such as photoshop. If you are looking to design the case ect get a template from interent and design over it, gives you the sizes and stuff.
Hope this helped and i understood the question right :)
Try using Epson Print CD.

Then use the drop-down box to select your operating system, press "GO", and it should appear on the downloads list. Note; all of these files are clean, coming from the original owners themselves (Epson).
Unfortunately the only way to be able to print using this software is to have an Epson Stylus R series printer I believe, but if you are looking to just design, then it could be the software for you. Photoshop is probably the best for CD case inserts, but I think there is another Epson program that you may be able to find called "Jewel" or something.
Hope this helps,
