I am all for it.

To be clear: I think both approaches 
* A widgetset as in LCL
* A custom-control set based on some existing framework
each have their advantages and disadvantages.

It's unfortunately too early to tell which approach will prove to be the
best. The former will be easier for people wishing to do a quick & dirty
rewrite of an existing desktop GUI. The latter is probably better for some
large new application. Only time will tell.
