No to a cooktop under a window for starters and unless we have an actual detailed floor plan I for one have no idea.

1- Cooktops under windows are a bad idea and not even allowed in some places.

2- You don't want your sink and cooktop opposite like that. It means two people cannot be using them at the same time

3- You typically want your fridge on the outer part of the kitchen for easy access without impeding traffic paths.

4- Dishwasher next to sink

5- I'm not a fan of sinks in islands but it's your call.

I don't like having either a sink or a cooktop in an island...I just want a big space to work (and some people like to have their kids sit on stools at the island.
Your dishwasher must be next to your sink.
A cooktop under a window means flammable window trim near fire or heat, and you can never have a window treatment.
I don't put the sink across from the stove or the refrigerator because when someone insists on helping me, they are in my way. Say "yes" to the help, but avoid collisions.
Always try to leave 48" or more between counters so you can walk around appliances when their doors are open...when you are unloading the dishwasher, removing something from the fridge or oven, for example.

How a bout an actual detailed floor plan if you really want help.

Another point regarding placing the cooktop under a window: cleaning grease off glass panes. Better nix that idea.
