Is it possible to create tooltips that are at an angle instead of horizontal.  I have a row or buttons and I want to show the tooltips above the buttons at an angle.  Then I want to be able to show all the tooltips together.  The effect is that a novice user can turn these tooltips on and still use the buttons.  So instead of a single tooltip showing up, all the tooltips display simultaneously until the user dismisses them.  Is this possible with any of the UI controls?

thanks.
