Good for you for deciding to help your 2 yr old become an independent potty-er! Potty training can absolutely be fun & enjoyable for both parent & child if you keep these things in mind:
1) Expect accidents and *value them* as a very important part of the learning process. Be supportive, matter of fact, and work as a team to clean up any messes. Never forget that potty training is a learning process (though many people like to say "she's not ready if there are accidents" that is simply untrue!). Have realistic expectations -- just like your daughter learned to eat food on her own w/ utensils or just like she learned how to go from crawling to walking to running. Sometimes there were messes, falls, stumbles, but each time she learned a little bit more about how to do it (eat, crawl, walk) independently. And so it is w/ pottying.
2) Stay relaxed, calm, supportive, loving - never shaming or pressure or irritation. You daughter absolutely wants to learn how to do this, and the more you make pottying seem as normal as breathing, eating, sleeping, the better. You don't need to do a whole bunch of fanfare (rewards, parties, dolls) to have a good time and to very successfully help your daughter learn to use the potty. Look at every pee/poop in the learning process (regardless of if it went into the potty, into underpants, or on the floor) as another step closer to being done with diapers. If you feel yourself getting too stressed out, take a break. Don't let your stress or impatience spill onto your daughter. It's ok to take a break (whether it's an hour or 3 days) as long as, overall, you're consistent with helping her learn to use the potty.
3) The more naked time you can give, the better. The more you use regular, plain cotton undies (instead of water-proof, absorbent diapers), the better. Your daughter will better understand cause/effect (hmm, I'm dancing around, I feel pressure down there, wow there's warm pee running down my leg - oh, potty!) and then be able to do something about it the next time (hmm, the last time I felt this, I peed down my leg... I'm going to try to get to the potty!).
Best of luck - happy pottying!
