TMobile and Verizon are incompatible. As are every other two separate phone services. The only way to use a TMobile sim card in a Verizon phone, is to get the Verizon "unlocked". You can do this at most mobile phone shops, but not all of them and most likely not an official Verizon or TMobile shop. This will cost you.

Can you buy an unlocked phone and make it a go phone with a go phone SIM card?

Sim Card SwitcharooMost phones that accept a SIM card can be unlocked and used for any service that uses SIM card technology. AT&T and Tmobile phones & SIM cards can be used in this way. However Tracfone and Net10 phones and SIM cards cannot. For AT&T and Tmobile, Prepaid or Contract makes no difference. I use my ATT / Cingular contract service SIM in a T-Mobile Prepaid phone. (unlocked of course). The unlocking bit, depending on the company that makes the phone, can get a little tricky; but if you put some time into searching, you can find the information you need for a small cost or most likely free altogether. I am leaving out info pertaining to technology compatibility as most state and abroad phones are GSM, and you most likely have a GSM SIM card.
