1. The Graphical Query Builder Graphic part is working right now, with simple joins.
2. User can select what columns to include in select sentence.
3. A SQL sentence can be generated from the graphical model.

Information about pgAdmin internal structure.
http://wiki.postgresql.org/wiki/PgAdmin_Internals
Information about my GQB internals
http://wiki.postgresql.org/wiki/Gsoc08-querybuilder-Internals
Right now, still there are a lot of works to do... but checking my proposal I'm on time:
I'm at deliverable 4, and the schedule for this it's about Jul 6 - 12,Jul 13 - 19 week 7,8
I hope this continue in this way.... and I'm going to try to create more posts on this blog...
Finally as an example of my work I publish two images of my progress using the dellstore sample database for postgresql
