No, it does not require a laptop. You can use Traktor with a regular desktop as well.
There are many places that one can download the software Traktor DJ Studio. There are two quality locations, however, that offer the best, easiest, and safest choice. One is to purchase the software from Native Instruments, directly. The other option is to visit CNET and commit to a trial use. These are places that one can download the software Traktor DJ Studio.

There is a few company who selling Virtual DJ software, however I suggest you to get a DJ Console to its funnier. For those type of software you can check online, there is two big company who sell this product. There is Virtual DJ they are up to version 6 and there is also Traktor of Native Instruments, but its expensive.
Serato is the most popular DJ system, but Virtual DJ and Traktor suppoort more external hardware. Try the demoes yourself and watch videos and decide for yourself.
For tabletop CD players, check out Pioneer CDJ 350's with a Pioneer DJM 350 mixer. If you want to use DJ software and a DJ Controller, check out the new Traktor S4 or the new Controllers from Pioneer. See following links...
Try using an audio converter from Nch audio. What version of Traktor are you using? I believe that the recordings are saved in MP3. DJ FLIP Housepartykings.com
I use Fruity Loops 9 XXL studio edition it does almost anything you want as long as you have the right plug ins. If that isn't what you are looking for i would suggest TRAKTOR Pro.
any newer laptop should do, as long as it has a good processor and a decent sound card.as for the software:Virtual DJ is a good DJ program ( not free)Mixcraft is a program for producers, so you can create loops and songs with it (not free)thenpurely for editing: audacity, a free program, very handy. (free, many addons with effects available)i don't know about free DJ / producing software
You can download software from the internet which will allow one to be a virtual DJ. However not all software is free and may require a payment in order to license it.
