gnomedb widgets need ability easy ability to popualte widgets from 
non-libda sources (proberly already possible). with possible tie-ins on 
sorting etc.  libgda api needs to be able to return field information 
attributes. API is a bit complex and messy compared with other simplier
data access libraries.  It has other things in there that proberly 
shoulnd't be sitting in libgda, though i imagine this is because of 
having to support a range of datbases and not just simply SQL.
