Hi Mark,
The UI is mostly built as a cross platform interface using OpenGL, rather
than using system-specific things like dialog boxes, however Factor has a
well used FFI interface that allows calling into C code cleanly and
easily. It also supports conditional compilation, you'll see we have
platform-specific vocabularies and words that dispatch via the type of
operating system.
One example of this is a cross-platform API to "trash" files, that on mac
goes to Trash, on windows to the recycle bin, and on linux to the
freedesktop trash spec:

We also have hooks for implementing logic on different CPU types, an
example using the RDTSC counter:

I'm sorry we don't yet have a cross-platform open-file-dialog and
save-file-dialog words, but it should be pretty easy to write and I made an
issue to track it:

Although I'm not sure when we'll have it finished and maybe you want to
contribute the Windows version if thats the platform you use?

We should probably make a UI test window that shows examples of all the
controls, that might exist but I'm not aware of it. Here's some code for
just opening a window and looking at a few gadgets:
vertical <track>
"This is a label" <label> f track-add
"This is a button" [ drop ] <border-button> f track-add
f "This is a checkbox" <checkbox> f track-add
"resource:extra/otug-talk/bi.tiff" <image-name> <icon> f track-add
T{ world-attributes
{ title "Test dialog" }
{ pref-dim { 300 250 } }
} open-window
