I guess I meant grid as in data grid to show data from a database, not layout. With wxWidgets it got tedious once you needed sorting, filtering or paging.
On the web I have a lot of choice, also in .NET. Not so much in qt or wxwidgets. I have seen some very nice Java desktop apps recently so maybe that's a good choice now despite a not so good reputation.
What do you mean with you don't have much choice with Qt? Its view-model architecture lets you basically use any source of data you like in the backend.
I am talking about UI widgets like grids with sorting, grouping, filtering, resizable headers or diagrams, charts, gauges and other stuff. On the web and in .NET you have dozens of choices that look very good whereas on qt I haven't seen much third party support.
