HELP NEEDED!

I'm making a novel called "Tell Me Your Wish" for my school project, but I haven't make the book cover. Can anyone help me make it? A pretty simple ones, but without any kpop idol picture on it XD. Oh, and I'm sorry to say this, but please don't credit yourself on the picture. I promise to credit you on the foreword of my fanfic story called "L.Joe Likes Me, But He's Not My Type". 

I'm really hoping someone will gladly help me, since I never know how to make any graphic pictures, especially for a book cover. Thankyou so much!

GOD BLESS YOU!~~
