nope.
qtractor does the lv2 external-ui extension only. this is the only lv2 ui

extension that is framework/toolkit agnostic.
it is my stance that all lv2 plugin authors should make their plugins

independent of the host implementation gui toolkit. the lv2 external-ui

extension delivers this independence. you can either do in-process or

out-of-process (like dssi), and most importantly you can do it on whatever

toolkit you believe sucks less.
nb. lv2ui:gtk plugins will only show on gtk hosts. lv2ui:qt plugins will

only show on qt hosts, if there will ever be one that supports it

specifically. qtractor won't be one of them, sorry.
fwiw, use the lv2 external-ui extension.
stay away from all gtk (qt) lock-in (lock-out) epidemics ;)
cheers
