Glad to hear you just jumped right in there and started some seeds to try your hand at growing from seeds! I hope they germinate and do well for you. If they do germinate, you might want to put them near a sunny window to get enough light.
One of the members here on ATP actually got a few blooms on some of hers while they were inside for the Winter. Hers were not young seedlings but instead mature single/double fans that she had purchased before Winter. You might find this article interesting:
