How make a binary, dicimal hexadecimal octal conversor

Hi guys, i really need your help with my project:

I need a program that convert a number to decimal, binary, hexadecimal or octal value.

I'am working on GUI and i have on my GUIDE the next things:

2 popupmenu

2 edittext

Well, i was thinking i could do a simple conversor (like google conversor).

And the edittext1 i enter the number to convert, then i choosee on the popupmenu1 what value is it(it can be decimal, binary, hexadecimal or octal value)

after that, i choose on the popupmenu2 what value i wanna convert and that value will be set on the edittext2.

I'am a beginner here,guys i hope you can help me with the code, please, help me with a code with the native variables(like edittext, popupmenu, etc).

Thanks ☺

I've attached a pic of my GUI.
