I would recommend you use Common Graphics.  CLIM is a long way from the
Windows look and feel.  CG applications are small, fast and zippy, with a
lot of Windows integration.  You can think of CG as a CLOS wrapping for the
Windows GUI API.

CLIM on ACL Windows doesn't interoperate with Common Graphics.

We are porting CG to ACL Unix on the theory that Microsoft has won the
desktop and hence we will use the WinAPI as our portability layer.  Several
companies are in this business supplying UNIX libraries with the Windows API.

CLIM does have some ongoing effort behind it, but it is a big task to make
it modern.  We would like to make CG an underpinning for a next generation
CLIM, but that is not a short term operation.

Regards,

Jim.
