Name says it all. Is it still relevant? I guess wxPython sort of counts. What do you think Daniweb? Now, I don't want to start a flame war -said every troll ever.

For cross-platform programs I don't know of anything newer or better. If you just want to start a new MS-Windows GUI program then C#, VB.NET or CLR/C++ Windows Forms are probably better.

It seems to me that Qt has pretty much "won" at this point. Occasionally, people will mention that wxWidget is a bit more light-weight or something like that, but for the most part, it seems that cross-platform GUI development is dominated by Qt now.
