Just an example of how I do it in my addons. Not saying it's right. But using a class and a loop to create some frames. Should be able to copy this into an existing addon and see the effect.

TestAddon = {}
MyFrames = {}

--Static frame class.
function TestAddon:CreateStaticFrameX(shade, x, y, xoff, yoff, name, parent)
	local self = {}
	self.frame = CreateFrame("Frame",name,parent)
	self.frame:SetPoint("CENTER",xoff,yoff)
	self.frame:SetSize(x, y)
	self.texture = self.frame:CreateTexture("ARTWORK") 
	self.texture:SetColorTexture(shade,shade,shade,1)
	self.texture:SetAllPoints(self.frame)
	self.frame:SetFrameStrata("HIGH")
	self.frame:Show()
    return self
end

for i=20,200,10 do
	local f = TestAddon:CreateStaticFrameX(0.2, 15, 15, i, i, "TestFrame", UIParent)
	tinsert(MyFrames ,f)
end
