Gantt-chart based project management

I really like the functionality that gnatt offers to be
able to show/determin when a project will be completed
in a consise form. What I don't like is having to
input all of that data myself and to update it when
values change.

I use gantt by myself to be able to track when I will
be done with specific assignments so I can show my boss
when I am overloaded and give him an estimate on when I
will have something done. But I have to use a seperate
time tracking application to keep track of how much
time I have acctually spent on a current assignments
and then at specific intervals I have to go back and
update the project scedule with that data. Having a
small time tracker that could integrate with and
update, either directly or indirectly, the gantt
project would be the ideal solution for me. I am an
expirencied java programmer and would be willing to
invest some time myself helping with this type of a
project. You can reach me at revans2 at gmail dot com
