Best way to render graphics

[samcrowleymusic]

All I would like to know is the best way for rendering rectangles, circles, coloured things on to the screen which are fixed to the camera in a GUI. I've searched and searched and I can't find how to do this. Can anyone let me know what the best way is to do this? It seems like there should be some easy way and I'm just missing something.

And how do I make it render something each frame, and at the end of each frame the screen is cleared so I'm not left with everything that's been rendered previously hanging around on the screen?
