As already mentioned here, the translation of libraries can be an issue, but one open source project that might help at some cases is:
http://alexalbala.github.io/Alter-Native/
Citation from its main page:
It provides a tool to easy port applications
from high-level languages such as .NET to
native languages like C++. It is a research project
and it is under development with the
collaboration of UPC - BarcelonaTech and AlterAid S.L.
