Thank you, that is what I was hoping for.

Well, my contribution so far has been intermittent. I first proposed
the GTK port almost 2 years ago, but it lapsed for want of time.
However, for the last several months I have been coding like mad.
In other words, I don't feel like taking up a position which requires
continuous attention. I work on DDD when I feel like it (and have the
time), and other projects at other times.
I should clarify that my day job involves computational electromagnetics
modelling on a small Beowulf cluster, but I'm not paid to do programming
full time (let alone open source). So I do it as and when... I don't
think I will be able to touch DDD again until mid-May, but after that
I'll have another go.
Meantime, here's another screenshot. I just got the "GDB Settings"
dialog more or less working...
