Hasta La Motion!

Hi, i saw some gizmos that are created in dylib format which is cool , it has custom feature that i’m looking for like creating custom viewer or can create your own onscreen control etc. If i want to learn about it, can anyone give the right direction, which good place to start, any valuable link u might know better. Any recommendation? i’ve been searching on the Net and as for developing in macos environment, i got directed to ‘Xcode’ (i don’t know whether i’m on the right path or not ? ), i got bunch of link, but most of them too general, i’m looking one that closely related to Nuke to be straightforward. Any suggestion will be great.

Thanx.
