So first of all, how much code is out there already that I wouldn’t have to get from GNU or other CopyLeft sources? How expensive is it?
Second, is there any textbooks or online courses you would recommend? What math should I learn?
Third, how do you get permission to import and export things like PSDs and Word documents?
Finally, what timeline should I keep in mind? How long does this stuff take to make? I’m not trying to make Adobe level stuff. The software is supposed to be pretty basic, at least for the start.
Give me the 101!
