I need urgent help with Windows Forms

Question

Hello, I need to make a program that recalculates a time in seconds to hours, minutes and seconds. The user specifies the time in seconds, clicks the Convert button and then gets the result, vs the time in hours, minutes and seconds. That's how it should look like. I was trying for 2-3 hours to figure it out, but I couldn't. I don't know if I am stupid or what. Can someone please make a program like this and help me with it? I appreciate it in advance!
