Have a look at the concepts in the tutorials and the capabilities of OpenGL. If there is no shadow casting in OpenGL, then try to come up with an idea how to model the shadow in OpenGL. Afterwards brush up your programming & general maths, logic & programming problem solving skills and then you'll have a concept and know how to implement it.

Sorry, if you don't even have a clue which road to take, then that project looks like as it's too hard for you. Also, it looks a little bit like homework of some sort.
