There's various code inside nm-applet that does this, but the easiest
way to do it is probably to (assuming an Ethernet connection):

#define DBUS_TYPE_G_MAP_OF_VARIANT          (dbus_g_type_get_map ("GHashTable", G_TYPE_STRING, G_TYPE_VALUE))
#define DBUS_TYPE_G_MAP_OF_MAP_OF_VARIANT   (dbus_g_type_get_map ("GHashTable", G_TYPE_STRING, DBUS_TYPE_G_MAP_OF_VARIANT))

NMConnection *connection;
NMSettingConnection *s_con;
NMSettingWired *s_wired;
char *uuid;
GHashTable *hash;

/* Create a new connection object */
connection = nm_connection_new ();

/* Build up the 'connection' Setting */
s_con = (NMSettingConnection *) nm_setting_connection_new ();
uuid = nm_utils_uuid_generate ();
g_object_set (G_OBJECT (s_con),
              NM_SETTING_CONNECTION_UUID, uuid,
              NM_SETTING_CONNECTION_ID, "Test connection",
              NULL);
g_free (uuid);
nm_connection_add_setting (connection, NM_SETTING (s_con));

/* Build up the 'wired' Setting */
s_wired = (NMSettingWired *) nm_setting_wired_new ();
nm_connection_add_setting (connection, NM_SETTING (s_wired));

hash = nm_connection_to_hash (connection);

dbus_g_proxy_call (proxy, "AddConnection", &error,
                   DBUS_TYPE_G_MAP_OF_MAP_OF_VARIANT, hash,
                   G_TYPE_INVALID);

g_hash_table_destroy (hash);
g_object_unref (connection);
