HEALTH COUNTER ON SCREEN?

Hi! :D
I'm having a bit of trouble with creating a health counter on screen for my game. What I'm going for is a health counter similar to the one you see in "Ib" because I would really prefer that over an actual battle screen with all the skills and turns and stuff. I have the pictures ready, I just don't know how to create it on the common event commands. I'm not the best with setting that up so would anyone be able to help me and tell me how to program that to work?
Thanks in advance!

It's a popular RPG Maker game made last February on RPG Maker 2000. It's about a girl who goes to the art gallery with her parents, only to find that she is the only one there. The paintings then come to life and she has to find a way out. It's personally my favorite RPG Maker game. :D

This is what I was going for, in the top left corner here. The most you can have is 5 and you lose petals as you take damage. When the rose wilts, you die. Here you go!
