what can I use? help, please

[Ivan Rodriguez Dorado <ivanrodo tsc uvigo es>]

Hello! I'm a student from Vigo (Spain), and I'm trying to use wxWindows in my 
Degree Proyect.

The fact is that in my application I need to be able to paint over several 
layers (or canvas, I don't know how it's named) and I haven't found the right 
way yet. 

I will explain you this: I need to paint a photo over one of this layers, and 
paint lines, or text over the rest of the layers (which should be 
transparent). So, I would see the photo and the text over it.

I think this will not be very difficult, but I can't find any class of 
wxwindows or any library easy to link with the rest of the application (which 
it's written in wxwindows). 

Thank you in advance. Have a nice day
