There are no such thing as a miracle: if you need some C++ code to be used, you will need to learn some C++, enough to understand it, or have someone to do this part of work.
You can re-use C++ code and bind it to your .NET application, but please don't think that you can do it without understanding. Maybe it will require deeper understanding of C++ than most of pure-C++ developers have, because many of them don't understand many internals, but all interop problems requires you to understand them.
You will need this knowledge to use P/Invoke.
If you need to learn P/Invoke, start from here:

This CodeProject can also be useful:
Essential P/Invoke[

The hardness of solution will depend on complexity of C++ interfaces. It can range from very easy to most tricky.
One alternative to P/Invoke is to use C++/CLI mixed-mode (managed+unmanaged) project. This project could build a DLL required by the global hooks, but it can contain some managed wrapper CLI code, so, from the standpoint of your .NET application, you can use it as a regular .NET assembly, that is, reference it. Please see:

^].
But note that this way will require you to learn both C++ and C++/CLI, yet another language. Ready to do some work? :-)
