Opening windows form from webservice

[pintu]

Hello friends,
i am creating an application using .net 2.0 and c#..My requirement is
to open a form which will take inputs from user to update one table
through web service..But my problem is that this should be done using
windows service..I have tried to find out the solution but failed to
open the form from windows service..(though i have alternative to open
a console application at startup and call webservice to do the
task.But i want to use windows service )
So is it possible to open a form from windows service..If possible plz
write some steps ..Its urgent..

Thanks in advance
