I think dotnet core with blazor is a good option these days. - C# can be used for all code, frontend and backend. - Several GUI frameworks/toolkits to choose from (mudblazor, radzen etc) - Cross-platform - High quality development tools from several providers - Code can later be reused in native applications for most platforms - Lots of documentation and tutorials available.
