It's all a bit new to me so a little scared!

As I read your post, I wonder if you're really referring to AdSense, rather than Adwords? Here are a few paragraphs to help you understand one versus the other:
AdWords: When you sign up for AdWords, you sign up to become an advertiser. When your ad appears, and someone clicks on it, that person is sent to your site - where hopefully they'll do business with you. When a user clicks on your ad, you pay a cost per click. You do not pay to have your ad appear, however.
AdSense: When you sign up for AdSense, you sign up to become a publisher. In other words, you publish AdWords ads on your site. When a user clicks on the ad, you as the publisher receive a portion of the cost per click that the advertiser pays.
If it turns out that you are actually interested in AdSense, then there is very active Forum here on WebmasterWorld dedicated to that program. You'll find it here:

AdWords or AdSense: either way, the better your site, the better things will likely work for you, IMO. And either way, best of success to you!

I was aware of the difference. Just thinking if I want to get a site up and running, how good it has to be to be acceptable to google. In other words, Google might not like sites that do not have lots of pages.
As for Adsense, I suppose a similar question applies to how good the site has to be to be accepted. If you are turned down, do you ever get a second chance?
