GTK used to be considered the bloated option along with QT. My first Linux box had 128MB of ram and it was screaming fast.

At one point I ran graphical linux on a 20 mb ram laptop although admittedly that was very tight.

I also remember running nt4 with photoshop, word, and my IDE (borland delphi) all at the same time and comfortably in 128 mb of ram.

What was the lean option?
