Here is what I suggest...
First, you should pick a word you're going to use, like "potty" or "outside". If she starts to go in the wrong spot get her attention by saying you're word.. let's just say it's "potty!" You can clap or make a loud sound to distract and stop her. Immediately put her in the correct place. When she goes in the correct place say "Good Potty!" in a praising tone of voice. That reinforces the word even more. It also helps to have the same feeding schedule each day and to give her plenty of opportunities to go potty.
DO NOT stick her nose in her pee or poo. If you can't catch her in the act it does no good to yell at her or stick her nose near where she went, she wont understand.
The main thing with puppy training is to associate good things with good behavior and bad with bad behavior. When she does something you like, give lots of praise or a treat. When she does something you don't like you can make a loud sound like shaking a can of pennies or slapping a rolled up magazine on something.
Another thought is, even though you are training her to go on a pad in the house, it may be a good idea to get her used to going on grass as well. I think it usually should take only a few weeks to housetrain a puppy.
Make sure you socialize her and get her used to anything you want her to be used to (car rides, different people, animals and surroundings etc).
I hope this helps. If you have any other questions feel free to ask. I love dogs. We are currently training our new Australian Shepard puppy (: Good luck!
