Python vs Java : GUI, drag an drop

[Jarek Wilkiewicz]

Hello,

I'm planning to write a UI application which will require support for drag
and drop (D&D). The user of my GUI will need to be able to pick a tool from
a palette and drop it into a workspace, move things around (a bit like in
Visio), resize, etc.
At present I'm considering using Java, the 2D API and Java D&D API.
Can I accomplish something similar using Python ? What graphic libraries
would I use ? Does it make more sense than coding the GUI in Java?

Thanks,
Jarek
