I have this code (Doesn't work at all)

static void initGl() {
    glViewport(0, 0, Display.getWidth(), Display.getHeight());
    glMatrixMode(GL_PROJECTION);
    glLoadIdentity();
    GLU.gluPerspective(45.0f, Display.getWidth() / Display.getHeight(),
            1.0f, 1000.0f);
    glMatrixMode(GL_MODELVIEW);
    glLoadIdentity();
    glClearColor(0.0f, 0.0f, 0.0f, 0.0f);
    glClearDepth(1.0f);
    glDepthFunc(GL_LEQUAL);
    glEnable(GL_DEPTH_TEST);
    glShadeModel(GL_SMOOTH);
    glHint(GL_PERSPECTIVE_CORRECTION_HINT, GL_NICEST);
}

public static void renderGL() {

    glViewport(0, 0, Display.getWidth(), Display.getHeight());

    glClearColor(0.0f, 0.0f, 0.0f, 0.5f);
    glLoadIdentity();

    glTranslatef(0.0f, 0.0f, -60.0f);

    drawCube();
}

public static void drawCube() {
    for (int x = 0; x < 100; x++) {
        for (int y = 0; y < 100; y++) {
            for (int z = 0; z < 100; z++) {
                glBegin(GL_QUADS);

                glColor3f(1, 0, 0);
                glVertex3f(-x, -y, z);
                glVertex3f(x, -y, z);
                glVertex3f(x, y, z);
                glVertex3f(-x, y, z);

                glColor3f(1, 0, 1);
                glVertex3f(x, -y, -z);
                glVertex3f(-x, -y, -z);
                glVertex3f(-x, y, -z);
                glVertex3f(x, y, -z);

                glColor3f(1, 1, 1);
                glVertex3f(-x, y, z);
                glVertex3f(x, y, z);
                glVertex3f(x, y, -z);
                glVertex3f(-x, y, -z);

                glColor3f(0, 0, 1);
                glVertex3f(x, -y, z);
                glVertex3f(-x, -y, z);
                glVertex3f(-x, -y, -z);
                glVertex3f(x, -y, -z);

                glColor3f(1, 1, 0);
                glVertex3f(x, -y, z);
                glVertex3f(x, -y, -z);
                glVertex3f(x, y, -z);
                glVertex3f(x, y, z);

                glColor3f(0, 2, 1);
                glVertex3f(-x, -y, -z);
                glVertex3f(-x, -y, z);
                glVertex3f(-x, y, z);
                glVertex3f(-x, y, -z);
                glEnd();
            }
        }
    }

All it does it freeze up the program and eventually it will render the red side of the cube. This obviously has to do with gltranslatef, but I don't know why that isn't working. My question is, how do I render multiple cubes at once? Are there any tutorials out there on voxel engines? Sorry for the horrible code, I realize I probably need a array to do this. I'm quite new at opengl.
