 Yes, but Qt3 is not free for proprietary use.

 FromName.Show works with me..?

 With my project it was easy.
 Tools menu --> Update forms.
 Then possibly some minor changes to code.
 Example Write and Read, see documentation for details.

 I think gb.qt4 is not completely ready yet. But in future you can, if
I have understand correctly.
 Qt3 <--> GTK+ works well.
