FontStyle.Bold should give you a hint.

The graphics classes won't take rich text. You need to position the bold words yourself and make them bold. You can use Graphics.MeasureString to work out where one word ends to put the next one in bold.

The idea is quite correct, but unfortunately OP will have problems using this method.
The problem is: Graphics.MeasureString is so inaccurate that there is a little hope to get smooth text. If you look around, you will see many UI GDI-based .NET applications where some texts are not fit in their clip regions (and hence clipped off) or overlap with other texts. This is because this method does not take into account things like hinting.

I used to use some more accurate code using some solutions I found of forums, but unfortunately, none of them (I mean only those using GDI) were not 100% accurate in my tests.

So, this is a problem which probably remains open, too bad...
