multicolmun grid

[Jose Eusebio Roza Pando <eusebio roza uah es>]

I work in windows :-( and i need show a matrix data completly. I have 
used CList but it is not that i need it. I would like a sheet widget 
like Excel or like GtkSheet in Gtk+Extra, but i need use it in windows. 
How can i do it, can i do it with Clist or similar?

I need draw a blocks (squares) set joins by arrows. The user may can 
move the blocks and the arrows will be draw automaticly.
how can i do it?

Cheers!
Eusebio
