First of all, don't use the PopupScreen. User interaction will go there instead of the "tipped" field which is not what you want.
Second, search the forum for "tooltip" - you'll find quite a few discussions on the topic, many with additional links and good replies.
In brief, you need a custom screen to which you add your fields. There needs to be a mechanism to somehow attach a tooltip descriptor to a field. Fortunately, you can associate any object with one using setCookie (and retrieve it using getCookie). The screen can implement a focus listener and track which field inside it has the focus currently. If the field with focus has a tooltip descriptor associated with it, the screen can take the position of the focus (getFocusRect), calculate how much room does the tooltip need, position it, set alpha to desired value and paint the tooltip on top of everything (after calling super.paint).
I hope that's enough food for though for now.
