Definitely.

Then you pass the -I flags specifying the library locations only to the
C compiler, not to the C++ compiler.

This has nothing to do with the possibility to include Gtk+ headers;
just your Makefile (or whatever you use) is broken.  So fix it and pass
the correct -I flags to the C++ compiler too (ideally obtain the flags
using pkg-config --cflags).

So, in addition, this other header is broken.  Headers that require
something to be #included should #include it themselves.  If it's your
header fix it.  If it isn't complain.
