Editing a Large Amount of Data Containing Many Fields

[Marshall Lake <mlake mlake net>]

I'm looking for a way to allow a user to edit multiple files of data. Each 
file contains many records/rows.  And each record contains many 
fields/columns.

I'm not deeply familiar with treeviews in GTK but from what I know it 
seems to me that using a treeview to facilitate editing many records 
containing many fields would be cumbersome for the user, especially 
getting from field to field.

If I'm wrong please let me know.  Maybe someone can point me to a GTK 
program which allows editing a large amount of data.

If there are alternatives in GTK for editing large data please let me 
know.

I would prefer to edit the data utilizing GTK but I'm open to any 
suggestions or ideas.

TIA.
