You can create your GtkTreeModel as if it was for a GtkTreeView,

But, don't use GtkTreeViewColumn, but GtkCellLayout.
GtkCellRenderer *renderer = NULL;
GtkTreeModel *tree_model = NULL;
GtkComboBox *comboBox = NULL;
  
   comboBox = gtk_combo_box_new ();
   if (comboBox) {
       tree_model = GTK_TREE_MODEL (gtk_list_store_new (3, G_TYPE_INT, 
G_TYPE_STRING, G_TYPE_STRING));
       if (tree_model) {

          renderer = gtk_cell_renderer_text_new ();
          gtk_cell_layout_pack_start (GTK_CELL_LAYOUT (comboBox), 
renderer, FALSE);
          gtk_cell_layout_add_attribute (GTK_CELL_LAYOUT (comboBox), 
renderer, "text", 0);

           renderer = gtk_cell_renderer_text_new ();
           gtk_cell_layout_pack_start (GTK_CELL_LAYOUT (comboBox), 
renderer, FALSE);
           gtk_cell_layout_add_attribute (GTK_CELL_LAYOUT (comboBox), 
renderer, "text", 2);

           gtk_combo_box_set_model (GTK_COMBO_BOX (comboBox), 
GTK_TREE_MODEL(tree_model));
       }
   }
