NVM! Didnt tried the Pawn Shop at Ishad 'Na. Theres a Thief Guild where the Rogue can join.

Hello! Your rogue can be inducted into the Warrior's guild. I used to play this game way back when it first came out. If you choose the correct roles and the timing is right, every character in your roster can be in every guild. It is a bit tricky, but it can be done. Good luck! :)

However, a lot of the cheats you see for unlimited gold, max HP (using the Toughen spell), keeping quest items, etc. do not work with the GOG W&W game. Only the original game (with installation CD's). I also figured out how to get unlimited experience points in the original W&W game, but again... it will not work in GOG. You used to be able to right click or just click on your characters while the shop owner/town hall governor, etc. is speaking to gain more experience points. A lot of the cheat "bugs" just don't work anymore.
