Do windows API work with windows form

I am trying to create a mini task manager where I can show all the process and details. I am able to get all the details by using CreateToolhelp32Snapshot, OpenProcess etc. Now for GUI I am not sure what to use? I can use windows form or windows APIs. Windows forms can make my job easier but I read somewhere that windows form won't work with win apis We can't mix m开发者_如何学Canaged and unmanaged code(I am not sure. I don't understand much of this). Can anybody guide me what to do in this? Can I use the forms or I can only use APIs. Is there any better way of doing this, kindly help me. Thanks in advance.

You can use both together.

Simply choose what you you are familiar with. The goal is to make it done and working, isn't it? :-)
