Dear ImGui is a great library, and immediate mode GUIs work really well for "data-centric applications" that don't want to replicate their primary data model in the terms of a UI framework.
But for a standalone app you'll need much more. You probably need file dialogs, you might need working menus (ImGui can draw menus, but provides nothing in the way of keyboard shortcuts), you might need translations, you might need accessibility -- in terms of accessibility ImGui apps are literally just a framebuffer. Nothing, nada.
