Tooltips on icons

Is it possible to get a tooltip to pop up with some text taken from a
field in my Postgis database when the user puts her mouse over an icon
in a layer?

I'm imagining you probably need to do something with JavaScript or
similar, but I wondered if there's already some sort of functionality
that helps, as it seems a fairly common functionality.

Thanks for any help that comes my way.
