I'm not familiar with slax, but generally you will find wine in a hidden folder in the home directory. Try this in a terminal; 'wine notepad' or possibly 'wine notepad.exe'.
Notepad and minesweep should be included in wine, after that you have to install programs.
That pretty much exhausts my knowledge of your questions
Edit/ OOPs,I'm an idiot,QW.EXE should also work.
