LibWidgetFactory is a library that simplifies using the AceGUI widgets. Below are some examples of it in action. For a more complete view take a look at how I did my options in Buffzilla.

local wf = LibStub('LibWidgetFactory-1.0')

local scaleNotifier = wf.factory('Slider', {
	key = 'scale',
	parent = frame,
	label = L['NOTIFIER_SIZE'],
	width = 160,
	min = 0.5,
	max = 1.35,
	isPercent = true,
	get = getOption,
	set = setOption
});

local item_threshold = wf.factory('Dropdown', {
	key = 'item_threshold',
	parent = frame,
	label = L['Item quality threshold'],
	tooltip = L['The item quality threshold for what should be sold.'],
	values = {
		[ITEM_QUALITY_POOR] = L['POOR'],
		[ITEM_QUALITY_COMMON] = L['COMMON'],
		[ITEM_QUALITY_UNCOMMON] = L['UNCOMMON'],
		[ITEM_QUALITY_RARE] = L['RARE'],
		[ITEM_QUALITY_EPIC] = L['EPIC']
	},
	get = getOption,
	set = setOption
})

-- create a overlay blocking out the interface options panel
-- useful for creating dialogs in your options frames
local dialog = wf.dialog(frame)
