fast multiple texts above graphical screen

[Howie]

Hi,

to show some (Unicode) texts in a graphical program (both: OpenGL / DirectX) i need to show several texts (also with a background color) above the graphic screen. Is there a fast way to create (mode less) little frame-less windows with only a text and background color. The application is an atl-activex-control. MFC is available. The text(or position) should be updated fast, if the scene is rotated or zoomed as example. The look and feel is basically like a tooltip.

Is there a recommend way to create this text-windows ?

Thanks in advance,

Howie
