Toolkits for developing Web Services in C++

[Amin]

I'm new to Web Services. I want to develop WS in C/C++.
I've worked briefly in MS .NET and Borland C++ Builder 6.
But they both didn't work well with my applications as they use some
libraries developed in MS Visual C++ 6.0

So can anyone guide me about other WS toolkits that work fine with MS
VC++ 6.0?

It would also be of great help if you also comment on pros/cons of
these toolkits? And also a comment on how easy the are to handle and
work with.

Thanks ... zeest
