Fill memo with google results in Delphi

I'm new to this so I hope you'll understand what i mean. I have a task - Create a program (in Delphi) with 2 textbox's on a form (memo's) and 2 buttons (show, save). When we write keywords and index in memo1 (example: car, 1) and press button show, memo2 has to return first result (URL) of google search. So if I type "car, 4", memo2 has to return the 4th result of google search. if we press save button, it has to download parsed page.

I've been googling it for days and still nothing.. Please help!
