Hello. I think you need to read a tutorial first: 
http://scentric.net/tutorial/treeview-tutorial.html

An example from there:

  GtkListStore *treestore;
  GtkTreeIter   iter, child;

  treestore = gtk_tree_store_new(1, G_TYPE_STRING);

  /* Append an empty top-level row to the tree store.
   *  Iter will point to the new row */
  gtk_tree_store_append(treestore,&iter, NULL);

  /* Append another empty top-level row to the tree store.
   *  Iter will point to the new row */
  gtk_tree_store_append(treestore,&iter, NULL);

  /* Append a child to the row we just added.
   *  Child will point to the new row */
  gtk_tree_store_append(treestore,&child,&iter);

  /* Get the first row, and add a child to it as well (could have been done
   *  right away earlier of course, this is just for demonstration purposes) */
  if (gtk_tree_model_get_iter_first(GTK_TREE_MODEL(treestore),&iter))
  {
    /* Child will point to new row */
    gtk_tree_store_append(treestore,&child,&iter);
  }
  else
  {
    g_error("Oops, we should have a first row in the tree store!\n");
  }
