I seem to have deleted all my files while removing the wine from the home directory

rm -rf $HOME/ .wine I see a space there ... You nuked your home with that.

Does anyone have a clue how to recover/show my removed/hidden files?

Got a backup? If so use that. Otherwise ...

• do NOTHING with that system. N O T H I N G. Any change to that bit of the disk lowers your ability to recover anything from it.
• Boot up a Live DVD and install "testdisk" in it.
• Run testdisk and have it scan that partition.
• Start praying.

Here

rm -rf $HOME/ .wine  

There is a space between $HOME and .wine. So, it means that rm has to force (f) the recursive (r) removal of both $HOME and .wine.

So, you chose to remove all the things in your home folder :)

There is no "undo" option here, the best solution is to recover from a previous backup.

Or, you can try from a live file system to use testdisk and photorec in order to recover your data.

Please note that, if you used the computer after the disaster occurred, it is highly unprobable that you will succeed at it.
