So far as gtk (and C generally) are concerned, "$HOME" and "~" have 
no special meaning, they're just arbitrary strings.

Or

sprintf(WorkingPath, "%s/Project/", getenv("HOME"));

This isn't a work-around, it's what you have to do. More idiomatic 
for gtk might be

gchar *WorkingPath;

WorkingPath = g_strdup_printf("%s/Project", g_get_home_dir());

/* use the path, then */

g_free(WorkingPath);

Or see g_build_path().
