Not when using a query binding. But if you run the query in a background thread (via system.util.invokeAsynchronous), then you could use some visual change to signal that the UI is "busy", and remove the indicators when the query result is delivered (via `system.util.invokeLater).
See this older topic for techniques you can/should use:
I like making an indeterminate progress bar visible, combined with disabling the entry fields and buttons that set up the query.
