What I meant was no bindings to native widgets or other toolkits. DWT
(like SWT) uses the native widgets and needs an interface. I was
thinking of a toolkit where everything is provided by D and done in D
without any reference to native frameworks (Cocoa etc.).
Whatever API / bindings you use, please don't expose non-native UIs to
users (drawn from scratch, either mimicking the native UI or not). They
never completely integrate with the OS, subtly deviating from the native
behaviour in ways that range from awkward to infuriating, and are always
playing catch-up to the latest OS changes.
For instance, take Viber for the Mac: what could be a great application
(most of the complexity of a VoIP app isn't even in the UI), has awkward
behaviors (e.g., the scrolling panes don't implement rubber banding,
which makes them feel extremely unresponsive in OS X), badly imitated
controls (e.g., the chat text box context menu, in OS X at least), etc.
Features which are both complex and subtle like internationalisation
also tend to break.
The situation was already bad when the Windows, Mac and Linux interfaces
were, overall, pretty similar (many of the non-optimal design decisions
in apps with non-native UIs tended to appear where there were
differences, such as in OS X global menus vs Windows' per window menus).
With the trend toward newer and more diverse interface approaches, such
as attempts to try to bring traditional computers to touch screen
hardware, non-native UIs will tend to perform even worse, feeling even
more alien to the end users.
For me the main issue of fully custom UI isn't the visual aspect but the
ergonomic, it can be hard to let the OS compositor to resize/move custom
windows like natives ones.
Everything else isn't so hard to manage.
Take a look to QML with Qt Quick Controls :

A multi-plaform UI SDK will tends to unify the way ui works across a
larger devices panel.
