How to Set Properties from a table?

So Lets Say I'm making a table that will allow me to code in things at runtime. It would look like this:

local guiobjects =
{
	{
		["ClassName"] = "Frame";
		["Parent"] = game.StarterGui;
	};
};

How would I go about creating the instance and setting the Properties?

for _,gui in pairs(guiobjects) do
	local newGui = Instance.new(gui.ClassName)
	for i,v in pairs(gui) do
		if i ~= "ClassName" then
			newGui[i] = v
		end
	end
end
