Converting from borland c++ to gnu c++

No. Depending on what kind of conversion you expect, this is either
impossible, or so easy to do that no tool is needed.

g++ is a compiler only, it does not include any libraries. Also,
windows.h isn't really a Borland file - it is part of Microsoft
Windows. There is no equivalent in Linux. Porting Windows applications
to Unix is a hard job, and many alternative routes exist. You should
ask in Linux/Unix/X11 groups for help, since that is not a compiler
problem.
