I do something similar where I need to get a list index (effectively the
column number) from the column. I do it by "tagging" the column with the
value like this:

  for (i = 0; i < cols; i++)
  {
    column = gtk_tree_view_get_column(GTK_TREE_VIEW(treeView), i);
    OBJECT_SET_DATA(column, "list-index", (gpointer)i);
  }

Then to later get back the value from the GtkTreeViewColumn:

  listIndex = (int)OBJECT_GET_DATA(column, "list-index");
