From the title, you are just looking at Curacao? Or other places too?
By "as easy to dive from as Divi Divi" I assume you're talking about the typical all around dedicated dive resorts there are many of on Bonaire? (Stay on the water, amble out to the dive boat, hop in the water for a shore dive grabbing your gear on the way.) Curacao doesn't have as many of those as Bonaire does.
What are you thinking of budget-wise?
All West at Kura Hulanda Lodge is a nice place and good op. Bit further walk from rooms to dive shop than some places because of the way it's laid out but no biggie. Boat leaves from there for am 2 tank and pm 1 tank. Very nice shore dive from dock. I imagine you could hire a DM if you want one for some shore dives there, but you might discover after getting familiar with the place that you'll be fine with shore diving with your daughter there. Good place to do an OW. I think they have a tank pickup in the parking lot now if you want to shore dive other places, but it sounds like you might not be interested in that. One of it's drawbacks is its at the far west end of the island - which is nice away from the city and better diving out there in general, but further from a lot of restaurants/shopping/sightseeing if you want that too.
There used to be a resort Habitat Curacao which was great for this. It closed and was sold to a Dutch chain and renovated and is now reopened as Oasis Parcs Coral Estate. It looks pretty nice but I don't know what the dive op is like. The dive op that was there appears to have left and set up shop at a beach nearby, no idea why. Don't know what if anything has replaced it or what they might be like. But it would be a great physical setup. It's also a distance from town, but not as far as KH and much more reasonable to pop into town for dinner or whatever.
Lion's Dive/Ocean Encounters might also work for you. It's close to town and lots of stuff to do around there, water activities, aquarium, etc. I'm not crazy about the on site shore diving but it's there. (I've also never been crazy about Ocean Encounters as a dive op, they always seemed a bit nannyish and regimented for my taste. But as newer divers you might be fine with them, and in fairness I haven't had first hand experience with them in many years.)
The Royal Sea Aquarium resort is sort of in the same complex as Lion's dive and a little less convenient but not bad to walk over to the main OE dive shop at Lions Dive - it's a timeshare if you happen to have points of the proper flavor, or I imagine you could rent there too if you'd prefer more of a condo thing.
Sunscape Curacao is an AI with shore and boat diving that might be worth looking into. It's down the beach from Lion's dive and the dive op there is also OE.
Ocean Encounters also picks up at the docks of a couple other hotels, which isn't the same as staying at a dive resort but might be convenient enough depending how much diving you plan.
The Marriott has a dive op Sea Sports that is pretty well regarded and supposedly a decent shore dive that I haven't done. Not your classic dive resort, but a nice place in a good location near town, and the dive setup looks pretty good. However, I think it's closed for renovations and don't know when it's reopening. Sea Sports also services the Hilton nearby, but the Marriott is/was much nicer.
The already mentioned Dive Bus has a great rep and will pick you up many places in the area of town to take you on guided shore dives. So that's not like quite staying at a dive resort but might work for you, depending what you want. I think an op called "Relaxed Guided Dives" is similar. Probably a couple other like that that people could expand on if it sounds like something you're interested in.
