[boost] Java style GUI in C++

I am currently designing a GUI framework in C++ (initially targeting the 
Windows platform) that uses a model similar to that which Java uses in it's 
AWT and Swing libraries. Specifically:

[1] Being able to use constructors to create the windows/components. This 
means there is no need to explicitly call a Create method like in the MFC 
framework.

[2] The use of layout managers. I like the various layout managers in Java 
and how easy it is to construct complex GUI interfaces.

[3] The support for events via "listeners". This will most likely be geared 
towards key/mouse events and "action" events (e.g. when the user presses on 
a button).

[4] Support for windowed and windowless components. Windowed components will 
use the native controls where possible, allowing a natural look and feel. 
Windowless controls will be lightweight components that do not use a native 
component (a Window handle on the Windows platform); these will be useful 
for writing the layout managers.

At the moment, I have a basic working version that allows you to write the 
following:

int PASCAL WinMain( HINSTANCE, HINSTANCE, LPSTR, int sw )
{
   swing::JFrame frame( L"Swing JFrame!" );
   frame.setPane( new swing::JPanel());
   frame.setSize( 500, 500 );
   frame.show( sw );

   MessageLoop msg;
   return( msg.Execute());
}

This creates two windows: the main frame and a panel that is a child of that 
frame. The JFrame is created in the constructor, but is not displayed until 
show is called. Likewise, the JPanel is created inside its constructor and 
the JFrame.setPane method makes that window a child of the frame.

I would appreciate comments and ideas as to what people would like out of a 
GUI framework, especially one that will be multi-platform.

Regards,
Reece
