Desktop App Development
Web applications now are widely used as frontend, but in some cases desktop applications still needed. We did a lot of desktop application starting from C++Builder and Qt and C# nowdays. Mosly we preffer to use C#.NET, Java and Qt to build rich UI applicaitons for desktop platforms - Windows, Linux, MacOS
For Windows Desktop we prefer C#.NET but can also use Java or even Qt if it is needed by customer.
Java or Qt is solution for Linux desktop applications
Java or Qt still works also on Mac OS.
