If you want HUD stuff, I'd suggest either writing your own code or considering sswift's library, since it seems to be suitable for that.
All in all, basic HUD's (such as those used by FPS's, for health bars, meters, etc.) are extremely easy to write- look at my older project, the Vein Engine, for code to displaying panels and text via 3D- though unoptimized, it does the job.
