There was a girl in Highschool who was very proud of her Irish heritage, and she insisted that the word "Celtic" is pronounced "Seltic". I asked her why, and she say that was how it was originally pronounced. Interesting... but to satisfy this reason it's wrong. Not to be arrogant, but it is.
Caesar writes "tertia qui ipsorum lingua celtae, nostra galli appelantur" which means "the third [part of Gaul] by the language of themselves the celts, by ours they are called the gauls"
The letter C in Latin is pronounced as a hard C, as in cat, and not soft as in acid. We know this because we know that words in Latin like Caesar or Celtae translated into Greek were written as Kaisar or Keltoi.
The reason we pronounce it this way, and it is the first pronunciation IN ENGLISH, is because we derive that particular word from the French word "Celtique" pronounced "Seltic", but if you're trying to pronounce it as ancient Celts would, use a hard C.
