Looks like the controller is a customized arduino type board running an 8825 driver, so any GRBL software will work. Depending on your abilities, you may want to pickup a cheap Raspberry PI and run CNCjs or similar (there are a ton of Linux CNC options), you don't really want to drive the CNC from your computer, in the event something locks up (it's Windows after all....) or resource constraints on larger projects (not physical size, but lines of code size). That is the setup I use, Raspberry PI running FreeBSD and CNCjs (linux would be a much easier option for someone new to the Unix world, Ubuntu specifically).
As for Software, I use Fusion 360 (and there are literally 10000s of tutorials on youtube on how to design and use the software), it is free for hobbyists and start ups (so yes, you can use it for commercial purposes as long as your revenue is less than $500k a year.. I don't think that will be a problem, keep in mind, they did change the license recently, and I have not read the new license). I use it, because it integrates well with Eagle (another of Autodesks products used for designing printed circuit boards). Another totally free, completely open license, do with it as you will, make as much money as you want option, is Blender, its a great 3D modelling tool, but it has a steep learning curve, and a really busy interface. I used to recommend Google Sketchup, but they pulled the stand alone version in favor a a cloud based version, and I don't like that, as it removed the ability to use plugins that generated cut lists, now only available in the Pro paid version...
Other options, are using Openbuilds web based application (full disclosure, I have an Openbuilds lead 1010, but I have no affiliation with them other than being a member of the forums and a user).
