These are a couple of the Heroes you can play the story through with as each side of the war I believe. Then a minimap in the upper right that grows with thr R-Trigger. Add a list of about 4 general's names on the top left of the screen and their unit's healthbar along with you own - and then add a skill point par at the bottom of the screen.
You can't see the GUI in these pictures but there really isnt much GUI to the game. Here are some screenshots I pulled off the internet. No one plays this? OK, I will post some stuff about it for the heck of it then.
