Here is a windows wallet (GUI !!! ) for ZEN that i have downloaded, and it works. (be patient--at first you see no connects, nothing syncing..be more patient)
ALSO, i have successfully converted my zcl to zen using it. (yes, this is the eleos wallet, but with gui it is so easy to use. windows friendly!)
The secret to get you zen converted from zcl is NOT to do all the import, convert stuff from the menu...it doesn't work.
TO GET YOUR ZEN: run and sync the wallet. save the wallet.dat file somewhere (it should be empty anyway.). Put your ZCL wallet.dat file back in place of the zen wallet.dat file.
Run the wallet, watch your ZEN coins appear.
use the windows zip file from this link ( eleos-win32-x64.zip ) to copy my experience:

All, for a Windows GUI wallet - Zen Dev preferred - use the windows zip file from this link ( eleos-win32-x64.zip )
If you want a simple GUI overlay on Linux you could try (Not in any way linked to the Zen core team devs)
