Some code problems with my plugin

I am coding a plugin that changes the look of the wp admin page.
Currently I am coding the interface, and I am having some problems. as my site has a white screen with this plugin activated.
Below is the entire code, so if any coding ninjas could take a look and try and find any errors or missing brackets, ect I would be grateful.
