Dynamically create states and transition using Animator Controller

Hello, I have an assignment for my university to create an American Sign Language Dictionary using 3D animation of a human model and I have a real problem trying to find a way to dynamically (in runtime) create states and transitions (Triggers?) so the correct animations get loaded and played in succession according to an input text (using an InputField) a user inputs. I honestly have little experience with Unity and I don't really know C# (although I can understand C / C++ / C# / JavaScript code). Anything that may be helpful would be welcome. Thanks. :D
