I need to know how to load a uv map created on blender to be displayed in a openGL aplication. where i can create a caracter(texture+polygons) to be displayed in a openGL aplication and how i load this? i mean, what program i must use?.

first you need to create the character mapped with UVW Unwrap in blender.
Then, export it to a format that you can read, In that format, you need the vertices of the char, and the texture verts also.

And the you texture map those verts according with the texture verts like you will do it normally....
