Re: [Bulk] Octave bindings for GTK+

Hi Muthiah

This looks like a fine idea. However may I suggest that if you set about 
writing bindings to some graphics toolkit, it might be best to choose a 
toolkint which natively supports Windows and Mac. I know of at least 
two: fltk and wxwindows. It is hard to imagine, but there is some small 
minority of users who do not run Unix and X :)
