I'm doing iOS now, but for Win I would choose Delphi if the price was not absurdly high. WinForms, WPF, Silverlight does not produce a self sufficent app. Qt is a great choice for Win, but about $4k per developer/year (for self sufficent app).

Actually I would suggest the LGPL Qt if you can use that license. And it should be about 1500 EUR per year nowadays.

Ever tried Lazarus and Free Pascal? That might be a cheaper route for your Delphi/Windows paradise, no?

Cannot use Lazarus for DevExpress does not support it. Their amazing UI components and native nature of Delphi lets you build visually attractive and very fast and robust applications.
