Welcome to the community, @ 🙂 Nice how ChatGPT lays out the structure for you. Very cool.
So, all of the front end design e.g. header, logo, nav, dashboard, etc., would all be built in toddle. Basically, anything visual you want to see is your front end.
Your data is going to come from your database, which I assume BuildShip have built in (not used it personally myself) and you'd use APIs to request and post data back-and-forth between the front end (toddle) and the database (BuildShip).
Whilst you are building, you can add static data initially. This is a good way to test the look and feel before hooking stuff up and also means you're not overwhelming yourself with learning too many things at once.
I'd also recommend breaking your app into smaller parts and think in terms of components. For example, your site header would be a component, your nav menu a component, etc. This allows you to modify things at a granular level and reduce the amount of stuff you have on a page.
I'll see if I can share an example with you from my own app that might help you get thinking about stuff.
