Trouble with the IDE

Hi everybody, im sure this is going to be an easy fix but I can not seem to find the issue. I am working on the first project and within the IDE all I see is a blank screen. I have gotten to the point where I have placed new code and the string code into the appropriate files however, when I preview the layout it stays blank. I believe this is an error on my part in using the IDE I just cant figure it out. Below is an image of what I see and also the errors I have. Thank you for your time, I appreciate any help! (note: I have not yet finished the listeners part as I wanted to solve this issue first)
