For doing the lettering on the house to you have to use Stroke Fonts 
that you can manipulate with transformations inside your scene.   I 
thought I included examples of how to do this in the code I gave you 
that drew and labelled the axes. Here is some of my ancient code that 
used stroke fonts.  Feel free to use whatever you want from it.


Note how I push a matrix, position the text, draw the text, and then pop 
the matrix.


void drawParticleAnnotation()
{

     int i, len;
     char message1[] = "Fermion";
     char message2[] = "Interaction";

     void *font = GLUT_STROKE_ROMAN;

     glPushMatrix();
     glColor3f(1.0,0.0,0.0);
     glTranslatef(.5, 0.5, 1.6);
     glRotatef(135.0, 1.0, 0.0, 0.0);
     glRotatef(180.0, 0.0, 1.0, 0.0);
     glScalef(0.003,0.003,0.003);
     len = (int) strlen(message1);
     for (i = 0; i < len; i++) {
         glutStrokeCharacter(font, message1[i]);
     }
     glPopMatrix();


     glPushMatrix();
     glColor3f(1.0,0.0,0.0);
     glTranslatef(.5, 0.8, 1.25);
     glRotatef(135.0, 1.0, 0.0, 0.0);
     glRotatef(180.0, 0.0, 1.0, 0.0);
     glScalef(0.003,0.003,0.003);
     len = (int) strlen(message2);
     for (i = 0; i < len; i++) {
         glutStrokeCharacter(font, message2[i]);
     }
     glPopMatrix();
}
