That is a bunch of Buttons, Textfields, Dropdowns and Listviews? How hard can that be in Cocoa?
In their blog post they said they worked for three years on the Mac version ... maybe the company is just one person not having much time or coding experience. Maybe I am underestimating the problem, but in my time they would have just hired a student or the nephew of their neighbor to hack something together useful.
They also mention in another post that four different contractors gave up on migrating it, three targeting Cocoa and one Qt. Maybe the codebase is brittle and hard to work with and not really worth the effort.
