How to create a basic window using c++

Hello all.

This is day one for me developing for the psp.

Ive managed to set up a working environment using eclipse and did all the basic dos-like thingies (sound, image, pad and ish)

ive used a little c++ before and i've got years of experience with c#, java and scripting and i've been using FlatRedBall (a XNA engine) for years.

Well, what i really want is a basic tutorial on creating guis for the psp using c++.

Can anyone help me? google wont tell :(

so...no one has created a window for psp?

Can't you just search for the sourcecode of a shell?
