Opengl qt

I am trying to display a 64x64 in opengl. The texture loads but I cant get it to display in a square and on the top left corner of the screen. Heres my code for the GLWidget in qt

#include "glwidget.h"

GLWidget::GLWidget(QWidget *parent) :
    QGLWidget(parent)
{
}

void GLWidget::initializeGL(){
    glClearColor(1, 1, 1 , 0);
    gluPerspective(45, 640/480, 1, 500);
    glEnable(GL_MULTISAMPLE);
    glEnable(GL_AMD_performance_monitor);
    glEnable(GL_TEXTURE_2D);
    GLWidget::loadTexture2(":/images/Block.bmp", GLWidget::backgroundimage);
}

void GLWidget::paintGL(){
        glClearColor(0.4f, 0.1f, 0.1f, 1.0f);
        glClear(GL_COLOR_BUFFER_BIT | GL_DEPTH_BUFFER_BIT);
        glBindTexture(GL_TEXTURE_2D, backgroundimage);

        glBegin(GL_QUADS);
            glTexCoord2f(0,1); glVertex2f(0, 0);
            glTexCoord2f(0,0); glVertex2f(0, 64);
            glTexCoord2f(1,0); glVertex2f(64, 0);
            glTexCoord2f(1,1); glVertex2f(64, 64);

        glEnd();
    glFlush();
}

void GLWidget::resizeGL(int w, int h){

}

QImage GLWidget::loadTexture2(char *filename, GLuint &textureID){
    glEnable(GL_TEXTURE_2D); // Enable texturing

    glGenTextures(1, &textureID); // Obtain an id for the texture
    glBindTexture(GL_TEXTURE_2D, textureID); // Set as the current texture

    glPixelStorei(GL_UNPACK_ALIGNMENT, 1);
    glTexEnvf(GL_TEXTURE_ENV, GL_TEXTURE_ENV_MODE, GL_DECAL);

    QImage im(filename);
    QImage tex = QGLWidget::convertToGLFormat(im);

    glTexImage2D(GL_TEXTURE_2D, 0, GL_RGBA, tex.width(), tex.height(), 0, GL_RGBA, GL_UNSIGNED_BYTE, tex.bits());

    glTexParameteri(GL_TEXTURE_2D,GL_TEXTURE_MAG_FILTER,GL_LINEAR);
    glTexParameteri(GL_TEXTURE_2D,GL_TEXTURE_MIN_FILTER,GL_LINEAR);

    glDisable(GL_TEXTURE_2D);

    return tex;
}
