If you're under Windows, you might be interested in the CSML tool. It 
allows you to build quite easily your own binding to .Net libraries. The 
CSML distribution contains an example of a mini-binding to Windows 
Forms; you can also see that in screenshots:

LexiFi uses CSML to build Windows Forms application, but most of our 
GUIs are managed by a higher-level layer, not direct calls to Windows 
Forms.  As a matter of fact, we generate most of the GUIs that are 
intended to show or edit structured values, automatically from OCaml 
type definitions.

We have a few local extensions to the OCaml compiler that makes it 
easier to build nice APIs for GUI toolkits, with a functional flavor: 
implicit subtyping and generalized recursion. Hopefully, I'll be able to 
blog about these extensions and how they are used for GUI programming 
some day.
