Texture a Sphere in OpenGL

Question

I'm not sure how to texture a sphere in OpenGL without using external image loading libraries. Is this possible?

My sphere is as follows:

glPushMatrix();
    GLUquadricObj *qObj = gluNewQuadric();
    gluQuadricNormals(qObj, GLU_SMOOTH);
    gluQuadricTexture(qObj, GL_TRUE);
    glTranslatef(0, translation, 0);
    gluSphere(qObj, 1.0f, 24, 24);
glPopMatrix();

I'd like to only use built in libraries, which poses an issue when searching online for solutions.

Can anyone lead me in the right direction?
