Yes.

Yes, but it's not a trivial thing.

I recommend you look at omniORBpy, which is the version of omniORB for
Python. It does exactly what you are suggesting -- it has a back-end
for omniidl that outputs Python code, and a module written in C++ that
provides a Python interface to the facilities of the C++ ORB library.
As you'll see, there's quite a lot to it.

What language are you wanting to use?

Cheers,

Duncan.
