Voor het bouwen applicaties maken wij o.a. gebruik van Delphi 

Delphi for Win32 is the only IDE that supports creating native code applications compatible with Windows 2000, XP, and Vista. This gives you the flexibility to use the OS the best suits your needs, while still developing for other popular Windows platforms. Delphi for Win32 enables development of Vista supported applications from the familiar Win32 environment, easy creation of web applications that support AJAX, and streamlined enterprise database connectivity.
