custom fields for a tutorial site

planning a tutorial site and will have several pre field like “time”, “what you need”, etc. so would like to just have a field when writing a post to put this info in instead of messing with the HTML everytime.

im wondering if anyone knows a good way to make this possible? i was thinking custom fields but ive no idea where to start, and how that would implement into the view. would appreciate any direction, and probably there is a plugin out there already i dont know about!
