Here's how to add a Google Account on your device:

1. Open your device's main Settings menu.
2. Under "Accounts", touch + Add account.
3. Select Google .
4. Choose Existing (if you want to add an account you already have) or New (if you want to create a new one).
5. Follow the instructions to add your account.

After you've added your account, to buy items on Google play, add Google Wallet to your account by signing in to your account at wallet.google.com.
Tip: To help prevent accidental or unauthorized purchases, use password protection on your account.

If you haven't already done so, create an account by applying a user name and password you'll remember.

Otherwise, you sign in to youtube with the username and password you created.

Hi
The only reason I can think of for your iPad not signing into Google when your Mac can is that the credentials being entered are not the same in both cases. The username should be the same as this is easily checked at each machine when you are on the log in page. The password is different as it is usually only shown on any screen as dots or asterisks. If you have saved the details on each machine then I would suggest that you check the usernames are the same and then change your account password using the Mac and the instructions below.
Log in to your Gmail account, click on the cogwheel to the top right of the window, and click "Settings" Click on the Accounts and Import tab and the password options, including changing the password are the first options on the list.
Having changed the password you can log in again from the Mac and then try logging in on the iPad using the new password.
Hope this is helpful, if so would you please register that with Fixya
Cheers

Gmail and Apple IDs are completely separate. You must have a valid account in order to login to either account. Be sure to check your credentials by trying to login online on their respective home pages. www.icloud.com for your apple ID and https://mail.google.com for your gmail account. If what you are typing in does not work online then you will have to recover your password by selecting "forgot my username/password"

I'm assuming you don't have the Netflix application installed. You'll need to download it from the Google play store am application that should already be installed. then sign into it(Netflix app) if you already have an existing account. If not then you'll need to create one.

On the Google sign-in page, click the "Need help?" link.

sign into google/gmail and remove accounts - you need secure information to remove or delete accounts. Otherwise Gmail/Google will not delete them. Learned from past experience.

Try opening the web browser and visiting http://www.google.com. You should be able to sign up from there and then you will have an account.

Hope that helps!
