Create Text Frame with Player's Health

[nibsrs]

Hey guys, I have zero knowledge in LUA scripting, however I am trying to know a bit more about it. I want to create a simple text on screen which will show the current player's health.
This is what I've done so far, but got stuck:

local f = CreateFrame("Frame", nil, UIParent)
	f:SetWidth(1)
	f:SetHeight(1)
	f:SetAlpha(1)
	f:SetPoint("CENTER", 0, 0)
	f.text = f:CreateFontString(nil,"ARTWORK")
	f.text:SetFont("Fonts\\FRIZQT__.TTF", 14, "OUTLINE")
	f.text:SetPoint("CENTER", 0, 0);

From here I don't know where to go, can someone help?
