Not to note that you fork twice!  And fork returns -1 on error.

You've left out a lot of details. You need to register a singal handler for
SIGCHLD. If you want to communitate with the child process, you have to setup
pipes etc.

It's better to use one of g_spawn_async or g_spawn_async_with_pipes or
g_spawn_command_line_async. They take care of a lot of the details for you.
