Qt vs Lesstif

[claudia e carniado rodriguez]

Hello.
I am a beginner in Linux and Lesstif.
I installed with no problems at all the latest version of Lesstif. I ran a
little example and it executed ok. 

My question is a very simple one: I know there is another thing called Qt. Can
you please be so kind as to tell me some differences and advanteges of Lesstif
over Qt?   

Thanks in advance. And congratulations for your job!!!!!!!
