I'm struggling with the custom lightning component on this part. I don't have much background coding and am having trouble finding resources to help me achieve coding the lightning component. If someone could help give me some framework code to create a custom lightning component to hold a URL or direct me to a resource that help break this down I'd be very appreciative.
 

Has anyone completed this trail? I am stomped on challenge number 3, regarding created the process for fulfillment. Any pointers or guidance would be appreciated.
