texture not loading properly slick java

texture is not loading properly it has lines and it is backwards. what is wrong. EDIT: I chopped some irrelevant code off so some things may look weird.

package package01;


import java.io.IOException;
import org.lwjgl.opengl.GL11;
import org.newdawn.slick.opengl.Texture;
import org.newdawn.slick.opengl.TextureLoader;
import org.newdawn.slick.util.ResourceLoader;


public class Graph {

    ...

public void initGraph(){

    ... 


        Texture strbutton,defbutton,vitbutton,intbutton,dexbutton,agibutton;
        try {
            strbutton = TextureLoader.getTexture("PNG", ResourceLoader.getResourceAsStream("/res/grphbuttons/strbutton.png"));
            GL11.glEnable(GL11.GL_TEXTURE_2D);
            strbutton.bind();
        GL11.glBegin(GL11.GL_QUADS);
            GL11.glTexCoord2f(0,0);
            GL11.glVertex2f(70,120);
            GL11.glTexCoord2f(0,1);
            GL11.glVertex2f(70,120+strbutton.getImageHeight());
            GL11.glTexCoord2f(1,1);
            GL11.glVertex2f(70+strbutton.getImageWidth(),120+strbutton.getImageHeight());
            GL11.glTexCoord2f(1,0);
            GL11.glVertex2f(70+strbutton.getImageWidth(),120);

        GL11.glEnd();
            GL11.glDisable(GL11.GL_TEXTURE_2D);
        } catch (IOException e) {
            e.printStackTrace();
        }

    ...

    }
}

This is the main class

package package01;

import org.lwjgl.LWJGLException;
import org.lwjgl.opengl.Display;
import org.lwjgl.opengl.DisplayMode;
import org.lwjgl.opengl.GL11;

public class DisplayScreen {
CharCreateScreen ccs = new CharCreateScreen();


void start(){
    initGL(1000,562);

    while(!Display.isCloseRequested()){
        ccs.openccscreen();
        Display.update();


    }
    Display.destroy();
}
void initGL(int width, int height){
    try {
        Display.setDisplayMode(new DisplayMode(1000,562));
        Display.create();
        Display.setVSyncEnabled(true);
    } catch(LWJGLException e) {
        e.printStackTrace();
        System.exit(0); 
    }

    GL11.glClearColor(0.9f, 0.9f, 1.0f, 0.0f);


    GL11.glEnable(GL11.GL_BLEND);
    GL11.glBlendFunc(GL11.GL_SRC_ALPHA, GL11.GL_ONE_MINUS_SRC_ALPHA);
    GL11.glLoadIdentity();
    GL11.glOrtho(-500, 500, -281, 281, -1, 1);
    GL11.glMatrixMode(GL11.GL_MODELVIEW);
}


public static void main(String[] args){

    DisplayScreen ds = new DisplayScreen();
    ds.start();

}
}

I keep encountering problems with loading the texture to slick, what's the problem this time? Can't I just load the image and put it on the screen without having this weird applying to textures? I'm only using slick to be able to upload a few images to use as buttons is there an easier way.

Here is what comes out. https://i.sstatic.net/onto1.png The button is labeled 'STR' or at least it should be. And what are those lines on the top and right?!

Make sure your textures sizes both width and height are so to say 2^x, such as 64x32, 16x16, 512x1024... (1, 2, 4, 8, 16, 32, 64, 128, 256, 512, 1024, 2048, 4096, 8192, 16384, 65536, ....)

NOTE: The texture file has to have those dimensions, however, you can render it at any size

Try change it to 

GL11.glTexCoord2f(0,0);
GL11.glTexCoord2f(1,0);
GL11.glTexCoord2f(1,1);
GL11.glTexCoord2f(0,1);

From

GL11.glTexCoord2f(0,0);
GL11.glTexCoord2f(0,1);
GL11.glTexCoord2f(1,1);
GL11.glTexCoord2f(1,0);

Didn't have a good look at your code though.
