is it possible to create a guide on labview interface to tell user how to use my program?

Basically this is the image of the project I'm working on and i want to know if I am able to create a guide that pop out telling the user which button does what when I run the program.

Yes, you can create a help window (use One button dialog as a start) which you can have as a sub vi with text indicator displaying your guide.

A better way of explaining what each Control does and an Indicator displays is by using the Tip strip.

I am pretty sure the Tip Strip is what you are looking for.  If you go into the control properties and go to the Documentation tab, you will see an input to Tip Strip.  This should do exactly what you want.

If you wanted more control of the messages appearance you could use String Indicators with Default text written to display what you want, placed near each object on your panel.  Then hide the string indicators.  Use mouse-over events for each item to show/hide the corresponding string indicator "help window"

This will give you more control over text size, font, message box border, etc.
