I don't know exact measurements for everything (personally I just taste as I go), but here is a rough recipe for a good sauce you can toss wings in:
150g butter
250ml hot sauce (any sauce that is mostly chillies and vinegar is fine to use)
100ml ketchup or bbq sauce depending on the flavour you want
1/2 cup of brown sugar (idk weight of this)
Melt butter over low-medium heat in a pot and add all other ingredients listed together until sugar has melted. This is the base.
From here on add whatever you want, personally I use varying amounts of:
Siracha, cayenne pepper, paprika, garlic powder, onion powder, liquid smoke, tobasco, MSG, soy sauce, worcestershire sauce, mustard, honey, black pepper, salt or literally anything else you could think would work well in a barbecue sauce.
Remember you can add more, but not take it away.
Choose your extra ingredients and add to the pot and let it simmer away with an open top to thicken to your desired consistency, sitrring to mix sauce thorougly and to let the spices do their thing. Usually taking between 15-25 minutes. This sauce tends to be good for either tossing or dunking wings into, it isn't that thick but isn't that thin and is the perfect mixture of sweet and spicy. It is also extremely unhealthy since there is a lot of sugar and butter.
For oven wings (im not as good at the chicken bit), split the wings into drums and flats.
Create a dry seasoning of salt (decent amount), pepper (similar to salt), plain flour (this is like 70% of the mixture) and bicarbonate of soda (a few teaspoons).
Cover chicken with dry mix, like how you do a dry dredge for a deep fry batter, and arrange on a baking sheet for the oven, cook depending on size but I usually find 200 celsius for 18-20 mins skin side up, then flip and cook for another 10.
Try using greaseproof paper with oil on it so the skin doesnt stick, but ideally it crisps up enough in the first 20 mins so it doesnt when you flip.
I also like adding the chicken juices into the sauce.
