Windows Mobile Application Development

I have a hp iPAQ Pocket PC, and am trying to develop some applications on Windows Mobile 5.0 and/or Pocket PC 2003 platform. I am using Windows XP as my development platform, no previous SDK is installed on this PC.

Grateful if someone here could tell me what tools I need to use. I intend to use eMbedded Visual Basic (or eMbedded C++ ?, which one is more appropriate?). What SDK and other tools do I need?

I found Microsoft Development Resources WEB site has too much information that a novice like me won’t understand at all.

Thanks
