Hi,

Maybe a bit late (after reading all the messages on c.l.a.), but what 
should be in such a portable GUI?

There is the basic functionality like handling windows, dialogs, 
buttons, menus, etc.

But there is also a lot more which you can share under the GUI. Some 
examples (note I'm Windows user and did some contributions to GWindows):
- functional dialogs like: file open, pick a directory, choose a color
- keyboard and mouse handling
- what about Human Interface Devices (HID) like joysticks
- displaying (or even loading) images
- using embeded objects like an RTF based editor, IE or firefox for 
embeded HMTL and stuff like that

As soon as you need the more OS specific extended GUI functionality, the 
binding (to the OS library, which is mostly C) gets more complex. And 
this will be in general also not easy portable to an other OS.

So be carefull with a portable GUI, before you know you are building a 
library which is a combination of all know emulators (MinGW, Wine)
