Trying to make AH addon / update old addon. Help needed please.

[Mahakali]

Hi there.

I am trying to make a simple yet complicated for my lua knowledge addon, that adds a frame/window to the already existing default AH screen. Inside this frame I would like to display all my existing listed auction. I would like button as well that scans my auctions and display little red text next to them if they are been undercut with the option to cancel the current auction.

I know there is already existing addons for that out there, but I would love to make my own. I have knowledge in python, but none in lua. Please point me to the right direction.

Thanks.
