This is the wrong approach. Never, ever change autoconf generated
Makefile.

No, CC is supposed to be the c-compiler, CXX is the
Makefile-variable to be used for c++ compilers.

Yes, to outline one way:
* convert glade's main.c into a c++ file (e.g. copy main.c to
main.cc, and add appropriated extern "C" {} guards around the
#include lines of glade generated headers.) 
* edit src/Makefile.am to use main.cc instead of main.c and add
AM_PROG_CXX to the configure.in.
* Disable "Generate main.c" in glade's options.

A more sophisticated way is to put glade generated c-code into a
library and to link your c++-application against it.
