If you want to create your own file format, the zlib compression library
may be what you want.  It uses the same algorithm as gzip/zip (deflate)
and has what looks like a simple interface (I've never used it).  It
works on memory buffers, so file I/O and file formats would be up to
you.

The first link describes a c++ class for zlib which does almost exactly
what you want, only with no particular file format.
