Yes, you need a C compiler to build GCC from source:
http://gcc.gnu.org/install/prerequisites.html

This is a common technique, see
http://en.wikipedia.org/wiki/Bootstrapping_(compilers)

Most operating systems either have pre-built versions of GCC available
or provide another C compiler which can be used to compile GC.
