--create your frame
--(note, you don't have to give your frame a global name, you can pass nil as the second argument instead)
local frame = CreateFrame("Frame", "MyFrameName", UIParent)
 
--give your frame a size
frame:SetSize(150, 150)
 
--give your frame something to look like
frame:SetBackdrop({bgFile = "Path\\to\\texture"})
 
--give your frame a location on screen
frame:SetPoint("CENTER", UIParent, "CENTER", 0, 0)
 
--now make a fontstring for your text
--(again, a global name is optional)
local text = frame:CreateFontString("MyFrameText")
 
--give your text something to look like
text:SetFont("Path\\to\\font", 12, "NORMAL")
 
--give your text some actual text
text:SetText("This is my message to display.")
