Yes, but what if you set sensitive properties of a bunch of the 
widgets in the same time. Each time you have to write and call 
setSensitive() for each widgets. If you bind their sensitivity 
property to one single widget, you can only switch one widget's 
property, and others will set automatically.

void doWhenDownloadIsComplete1(){// a lot of code pollution
    but1.setSensitive(false);
    but2.setSensitive(false);
    .
    .
    entry2.setSensitive(false);
}

...

void doWhenDownloadIsComplete2(){ // nicer
    but1.setSensitive(false);
    // other widgets' sensitive properties are binded to of 
but1. No extra code needed.
}

Actually I have just tried this with gtkd and working:

button1.bindProperty("sensitive", entry1, "sensitive", 
GBindingFlags.DEFAULT);
