Drawing text to images

Question

I am developing software to run Church presentations to be displayed by the projector.
I need to apply text to an image in the manor that it is done in powerpoint.
I can draw text to an image, but my problem is how to draw text that is editable so that I may change,delete,redraw.
I may Have to code something totally from scratch. Any Suggestions???? Does anyone know how Powerpoint does it.
Thank you all in advance..

I Have been considering the problem with editing text and drawing editable graphics to an Image. I believe the approach I am going to take is to implement a layer drawing system, I just need to work out the transparency implementation, I know transparancy doesn't truly exist, even at the system level. but I believe it can be faked well. then I know I can save my layered image as a composite. Does this all sound like a good approach??? please any help???
