I would probably use Photoshop to do something like that. Just my opinion, but I'm sure 80% or more would use the same.
Photoshop is one of the option for designing such thing like that and also count on Corel Draw for vector graphics.
If you've already got the images you want to put on the box you can probably get someone to do this for you at no charge.
This might be what you are looking for. http://www.trueboxshot.com/ I tried the demo, its easy enough Tinman
I can do it for you for just $15 for a box like that.. that's definitely using photoshop action script..
