Here is a screenshot from ~5 years ago when i was playing around writing a Quake 1 level editor in Delphi 2 under Windows 10[0] (i switched to using Linux as my main OS soon after and converted it to Lazarus[1]).

It's been a long enough time that the details have left my brain, but the feelings of pain have not been forgotten :-)
Did a bit of search, is it QuARK?
It is not QuArK, though AFAIK QuArK was made in Delphi too. There have been a few other Quake editors made in Delphi, like the qED Quake Editor which was one of the earlier Quake editors (the author wrote a book about quake mapping too[2]).
