Writing a C++ wrapper for gpgme could be an interesting project, though.
Still, you should know about new and delete, and arrays, even if you started
out with C++. malloc and free allocate and release memory explicitely as
the C++ operators new and delete do.

You need to add a binary 0 to the data object:
gpgme_data_write (output, "", 1);
and then the return value of gpgme_data_release_and_get_mem is a standard C string
(if the data is in armor format, of course, and does not contain binary
