Hello and welcome.
If you are just starting out, I'd start with a smaller area and not one acre.
It is a good idea to start planning a garden in the fall for the Spring.
No till is actually a good way to deal with grass. You can do sheet mulching. Either use a sod cutter and turn the grass upside down or lay thick cardboard over the garden area. You can make a border for the garden to help keep the grass out. Unless you want a large plot for corn. It is easier to lay the garden out in beds. Make each bed about 4 ft wide and 10 ft long. 4 feet wide is about as wide as you can make it and still reach across without having to walk in the bed. 10 feet long with breaks between beds makes it easy enough to get to the other side without going through the bed. Pathways between the beds can be mulched or you can leave the grass and make the aisle wide enough to still mow it. It is a good idea to make the aisle at least wide enough to get your wheel barrel, cart and tools through it. I would build one bed at a time and add to it as time and your skills allow you.
The bed should be near a water source and it is a good idea to maybe put irrigation in the beds at the same time.
You should have a compost area near the garden. It will be easy to compost your residues and a source of good compost for the future.
The following link explains what sheet mulching is all about. Sheet mulching is an economical way to build a garden using a lot of materials from your house, kitchen scraps, leaves, newspapers, (neighbors leaves and kitchen scraps). If that is not enough, ask a few more friends or ask the local grocer if you can get their produce they are going to throw out anyway, coffee grounds and filters from coffee shops. If you don't have enough browns, you can always get a bale of hay.

Plan out what you want in the garden and while you are stuck inside during the winter, you can do your research on each plant, its needs, days to maturity, and how many and how far apart they need to be planted.
There are apps for garden plans and some ready made plans.
Unless you are retired, and no one has planned your retirement for you, you have to decide how much time you have to spend working in the garden. You can't just plant it and forget it. You will need to spend some time every day on it, especially if you don't have an irrigation system and then there is the weeding, bug patrol, trimming, disease control, etc.
At first start with a few easy plants and then when you have mastered those add on. Add on additional beds when you have the time.
The first plants I would start with would be lettuce, I would only plant as many heads as you can eat in 10 days. Plant additional seeds and replace the heads as they are harvested. If you plant the whole packet you will have more lettuce than you can eat at one time. Kale and swiss chard are good because you won't need as many plants and they can be harvested more than once. Beets, carrots, cabbage, are other cool season crops. Herbs are good choices since they are expensive to buy and add so much flavor to dishes. Some of them can be kept in pots to overwinter. Choose what you like to eat, but take a chance sometimes and you might be surprised.
For short season growers, you need to have a greenhouse or basement or some indoor growing area to start seeds before transplanting them out. Peppers, tomatoes are usually started indoors in cooler areas. They don't like to go outside before the temperatures are over 70 degrees. The seeds don't even want to germinate in cool conditions.
Happy gardening in Hawaii. Gardens are where people grow.
