Hello, everybody.
I am a TOTAL newbie at XCode, yet I want to create a 2D animation software. My requirements are as follows:

importing quicktime video and/or jpg or png image file sequences,

multiple layers that are able to be locked and unlocked,

a canvas to see what I'm doing,

obviously, draw and erase tools and a color picker,

a timeline (duh),

a way to export the finished animation to quicktime,

And finally, "save", "save as", "undo", and "redo" commands.

Please help me, point me in the right direction, or something and i'll really appreciate it. Thanks!
