Hi everyone! I asked this earlier in the week, but I don't think I explained my question very well (sorry for the translation; I'm a Spanish speaker).

I want to learn how to develop graphical user interfaces (GUIs).

I'm generally new to programming, but I really like Rust; I don't know any other languages—just Rust.

I want to build a project for the company I work for. We mostly use Excel for our data; our "database" (an Excel file) is 500k rows by 25 columns (though there are several files covering different areas, so the total exceeds a million data points).

I want to automate this. That million data points is spread across years; the most critical process involves each of us reviewing 100 items in 30/40 minutes—classifying, validating, sorting, etc.

I need to create something like dashboards featuring:

charts and tables that are sortable and filterable.

These two components are absolutely critical.

For the rest, I'm thinking of a data grid (something like Excel, but not a full spreadsheet—just small tables with editable cells).

We need this because our values ​​aren't always 100% accurate; there's a lot of human error involved in our work.

For example: Our system registers a client who has a discount percentage, but that wasn't included in the initial registration request. So, the discount doesn't apply the first time. Later, we receive the correction, and the discount applies to the second sale—at which point we also correct the first sale.

This happens across all areas, so I need something editable. Given our limited review time, I need the interface to be fast and intuitive.

I don't need mobile support—though it would be a nice-to-have, it's not essential. I need a recommendation focused 100% on desktop.

It also needs to properly support Windows, Mac, and Linux.

Which GUI crate would you choose? (I know it's difficult for me, but I want to learn a lot)
