Answer 1

All UIs must use UIKit, which is an Objective-C API. Back-end code can be written in C or C++ (Objective-C++ as well).

There are frameworks which provide a wrapper on top of UIKit, such as MonoTouch, which allows you to use C# to develop iOS applications. There are other solutions such as Titanium, or embedding a Lua runtime in your application.

You can also implement all of your drawing as OpenGL and use plain C or C++, with a thin Objective-C wrapper to receive touches, load system resources (files, etc) and generate the GL context.
