1. Use this code snippet so you can use just the window, you can adjust the size accordingly, but I kept it 640x480
set window on
title$="Your game name"
set window title title$
set window size 64,480
2. Health bars are pretty easy, like BatVink said, you can search the Code Base, or you can make up your own, using 3D plains like the "make object plain..." command. You can use variables and things to keep track, and even put in Save Games using .dll or just the write file command, and read file command.
