Programming Language for Mac OS X application [closed]

Question

I have an upcoming project coming up in which I want to dedicate several months to making a professional application which is basically a text editor with a special purpose (can't disclose too many details). The program shouldn't be too complicated, but I wanted it to have a nice GUI and be fast enough to sell from either the Mac App store or my website.

I was going to initially make it for Mac OS X and then later Windows and I wanted to know, for someone who is intermediate at programming, what language should I use for this program? Should I use a library? I already have a foundation in c++.

Answer 1

The standard programming language for Mac OS X is Objective-C, however, as a rock solid Unix descendant, it also has great C and C++ support. If you want to write an efficient, nice and native (OS X) look-and-feel GUI, I'd suggest you use Cocoa (it has Objective-C interfaces) which is Apple's default and official GUI implementation for OS X. Considering portabilitiy, however, you may also use some cross platform GUI/widget toolkit, such as QT, GTK+, etc. (which are also, in general, written in C/C++).
