Yes, it's very possible.
The steps to set it up are a little daunting if you've never tried adding your own macros before. It's well worth it because it makes Welsh accents very simple to use in Word. I have provided great detail and plenty of pictures to help you through the process. If you are not comfortable with following these steps then you should ask someone who isn't afraid of doing things to computers.
Just so you know what this gives you: You will be able to add any of the Welsh accents to vowels by first typing the vowel and then repeatedly pressing Ctrl+#.
By that I mean you press and hold Ctrl, press #, release #, release Ctrl.
This will be available in all Word documents, but not elsewhere in Windows.
Most recent versions of Windows are OK for these instructions. It should be fine with Windows 2000, XP, Vista, 7 and later.
Start Microsoft Word.
I am using Word 97 in Windows XP. All the options are available in other versions of Word. They may be a little harder to find.
I've recently used this for Welsh accents in Word 2010 and the macro still works without modification. I will update this page with some new screenshots because the user interface looks so different
From the menu, select >> >> .
Word will offer you a new macro called Macro1. If it has a different name in your version, make a note of it because we'll need it later.
Press .
From the menu, select >> >> .
From the menu, select >> >> .
Word will show you all the recorded macros.
Select our macro, which here is called Macro1.
Press .
Word will show you a very empty macro in its Visual Basic window.
Select all of Macro1 from the Sub Macro1() line to the End Sub line.
Delete Macro1 by pressing either the Delete key or the Backspace key.
Select and copy the following lines and paste them into the Visual Basic window.

Close the Visual Basic window.
You now have the macro for the accents. You just need to attach it to the keyboard and a toolbar button.
From the menu, choose >> .
In the Customize dialog, press the button.
In the Categories list, select Macros.
In the Macros list, select WelshAccent.
Click the mouse in the Press new shortcut key box.
Press Ctrl+# (i.e. press and hold Ctrl, press #, release #, release Ctrl).
Why have I chosen Ctrl+#? I chose it because it is easily available on a UK keyboard and Word hasn't already assigned anything to it. You are free to use any key combination you like but you will probably find that Word already has it assigned to another command.
Press .
You will see Ctrl+# in the Current Keys list.
Press .
In the Customize dialog, selct the tab.
In the Categories list, select Macros.
In the Commands list, select Normal.NewMacros.WelshAccent.
Use the mouse to drag the Normal.NewMacros.WelshAccent and drop it just to the right of the button.
You will see your macro as a rather big button in the toolbar. Let's make it look better.
Right-click on the in the toolbar and choose .
Your macro button is now a small flowchart picture.
Right-click on the flowchart button for in the toolbar.
Note that there is a menu option called You can try this if you're feeling creative.
For now, choose and choose the yellow smiley face. That should be appropriate with how you're feeling when you try this out.
Press .
You now have Welsh Accents easily usable in Word.
Close Word and reopen it. This will keep your macro changes.
Try it out by typing GreCtrl+#t, sgiCtrl+#Ctrl+#o, carafaCtrl+#Ctrl+#Ctrl+#n.
Once you've typed a vowel letter, you can repeatedly press Ctrl+# to change the accent, including removing the accent altogether.
If you prefer, you can press the smiley face button on the toolbar rather than using Ctrl+#.
Hwyl!
