Help in changing the GUI looks!

I downloaded a project from internet. Now I want to change the looks of the lobby a little. But I am a complete newbie to programming. So i want it to look little more attractive. My ideas are included in the photo. In available servers, the button should be changed to Connect and the text Host to Servers. On clicking dirctt connect tab, it should act like the button in the GUI script below. In the logo space i should be able to upload my Logo!

Here's the GUI Script.

using UnityEngine; using System.Collections;

public class HUD : MonoBehaviour { public PlayerVitals pv; public Weapon wep;

 // Use this for initialization
 void Start()
 {
     if (!GetComponent<NetworkView>().isMine)
     {
         this.enabled = false;
     }
 }

 // Update is called once per frame
 void OnGUI()
 {
     if (GetComponent<NetworkView>().isMine)
     {
         GUI.Label(new Rect(20, Screen.height - 40, 100, 40), "Health: " + pv.hitPoints.ToString("F0"));
         GUI.Label(new Rect(20, Screen.height - 20, 150, 40), "Ammo: " + wep.bulletsLeftRead + " / " + wep.bulletsPerMagRead + " | " + wep.magsLeftRead);
     }
     else
     {
         this.enabled = false;
     }
 }

}

Thanks in advance!!
